VHS Study Guide Psychology WEEK 1: Psychology as a Science The goal of this week is to distinguish between "Pop Psychology" (myths) and "Empirical Science" (facts). 1. The Philosophical Roots & "Big Names" Wilhelm Wundt: Established the first psychology lab (1879). He used Structuralism, trying to map the "structure" of the mind through Introspection (having subjects report every tiny sensation they felt). Sigmund Freud: Founded Psychoanalysis. He believed behavior is driven by the Unconscious mind and childhood traumas. He used dream analysis and "free association." Behaviorism (Watson & Skinner): They rejected Freud. They argued psychology must be an Empirical Science, meaning we only study what we can see and measure. Watson: Famous for the "Little Albert" study (fear conditioning). Skinner: Focused on how rewards/punishments shape behavior (Operant Conditioning). Ivan Pavlov: A physiologist who discovered Classical Conditioning (associating a neutral stimulus, like a bell, with a natural reflex, like drooling). Maslow’s Hierarchy of Needs: A Humanist theory. It’s a pyramid starting with basic survival (food/water) and moving up to Self-actualization (reaching your full potential). 2. The "Brain Traps" (Critical Thinking & Myths) Word-of-Mouth: We believe things just because we’ve heard them a lot (e.g., "We only use 10% of our brain"—FALSE). Desire for Easy Answers: People prefer a "quick fix" (like a 5-minute cure for anxiety) over complex scientific reality. Selective Perception: We only notice things that confirm our existing beliefs. Post Hoc, Ergo Propter Hoc: "After this, therefore because of this." The logical error of assuming that because Event B followed Event A, Event A must have caused it. Inferring Causation from Correlation: The most common exam trap. Just because two variables move together (like heat and crime), it doesn't mean one causes the other. Reasoning by Representativeness: Stereotyping. Thinking a person "looks like" a certain role, so they must be that role (the "Finance Bro" vest example). WEEK 2: Scientific Inquiry and Research This is the "How-To" of psychology. You need to know the difference between just watching people and running a real experiment. 1. Research Methods Naturalistic Observation: Watching subjects in their natural habitat without interfering. High "real world" accuracy, but you have zero control. Case Study (Clinical): An intensive, detailed look at one unique individual (e.g., a person with a rare brain injury). Great for detail, but you can't apply the results to everyone. Archival Research: Looking at old records, newspapers, or medical files to find patterns. Longitudinal vs. Cross-Sectional: Longitudinal: Following the same group of people for 20+ years. (Expensive, but shows true change). Cross-Sectional: Comparing different ages at the same time (e.g., testing 10-year-olds and 50-year-olds today). 2. The Experimental Design (The "Gold Standard") Inductive vs. Deductive: Inductive: Starting with observations $\rightarrow$ forming a theory (Bottom-up). Deductive: Starting with a theory $\rightarrow$ testing it with an experiment (Top-down). Independent Variable (IV): The variable the researcher manipulates (The "Cause"). Dependent Variable (DV): The variable being measured (The "Effect"). Control vs. Experimental Group: The experimental group gets the "treatment"; the control group gets a placebo or nothing. Random Assignment: Every participant has an equal chance of being in either group. This prevents Bias. Single-Blind vs. Double-Blind: Single: Participants don't know which group they are in. Double: Neither the participants nor the researchers know. This prevents the researcher from accidentally giving "cues." WEEK 3: Biology and Behavior The "Hardware" section. How the physical brain creates the "Pink Slime" experience. 1. The Nervous System Map Central (CNS): Brain and Spinal Cord. Peripheral (PNS): Everything else. Somatic: Voluntary movements (walking). Autonomic: Involuntary (heartbeat). Sympathetic: "Fight or Flight" (Eyes dilate, heart speeds up, digestion stops). Parasympathetic: "Rest and Digest" (Calms the body down). 2. The Neuron (The Building Block) Dendrites: Receive messages. Soma (Cell Body): Process info. Axon: Sends the electrical signal. Myelin Sheath: Fatty tissue that speeds up the signal. Synapse: The tiny gap between neurons where chemicals travel. Neurotransmitters: Agonist: A chemical that mimics a neurotransmitter (enhances the effect). Antagonist: A chemical that blocks a neurotransmitter. 3. Brain Tools & Anatomy EEG: Measures electrical brain waves (good for sleep studies). MRI vs. fMRI: MRI shows structure (a picture); fMRI shows function (where blood is flowing). PET Scan: Uses radioactive "tracer" sugar to see which parts of the brain are active. The Endocrine System: Uses Hormones (slow-acting chemicals) released into the bloodstream by Glands (like the Adrenal or Pituitary). 4. The "Hidden" Biological Details (Week 3) Refractory Period: After a neuron fires, it needs a tiny "recharge" break before it can fire again. Think of it like a camera flash or a toilet flushing—you can't do it twice in a split second. Broca’s Area vs. Wernicke’s Area: * Broca’s: Controls Speech Production (Frontal Lobe). If damaged, you know what you want to say but can't get the words out. Wernicke’s: Controls Language Comprehension (Temporal Lobe). If damaged, you can speak, but it's "word salad"—it makes no sense. WEEK 4: Consciousness Consciousness is your awareness of yourself and your environment. It’s not an "on/off" switch; it’s a spectrum. 1. Processing Levels Conscious Processing: Tasks that require focused attention (e.g., learning a new TikTok dance or solving a math problem). Automatic Processing: Tasks we do "without thinking" once they are learned (e.g., walking or an experienced driver steering a car). 2. Altered States Hypnosis: A state of extreme self-suggestion where a person is highly open to direction. Meditation: A practice of focused attention to achieve mental clarity and emotional calm. Daydreaming: A shift in attention away from the current task toward internal thoughts and "mental movies." 3. Psychoactive Drugs (The "Drug Cabinet") Depressants (Alcohol, Barbiturates): Slow down the Central Nervous System (CNS). They decrease heart rate and reaction time. Stimulants (Caffeine, Nicotine, Cocaine, ADHD meds): Speed up the CNS. They increase heart rate and energy. Opiates (Heroin, Morphine, Vicodin): Specifically target pain receptors. They mimic Endorphins to stop pain and create euphoria. Hallucinogens (LSD, Marijuana, Psilocybin): Distort perceptions and evoke sensory images in the absence of sensory input. WEEK 5: Sleep and Dreams Sleep is a biological necessity, not a luxury. Your brain is incredibly active during this "downtime." 1. Stages of Sleep (The Cycle) Stage 1 (NREM-1): Light sleep. You might experience "hypnagogic sensations" (feeling like you are falling). Stage 2 (NREM-2): Deep relaxation. Characterized by Sleep Spindles (bursts of rapid brain activity). Stage 3 & 4 (NREM-3): Deepest sleep. This is when the body repairs itself. If you wake up here, you’ll feel very groggy. REM (Rapid Eye Movement): The "Dream Stage." Your brain waves look like you are awake, but your motor cortex is blocked—meaning your body is paralyzed so you don't act out your dreams. 2. Dream Theories (Why do we dream?) Freud’s Wish Fulfillment: Dreams are a "safety valve" for unacceptable feelings. Manifest Content: The actual storyline of the dream (e.g., being chased by a giant Pink Slime). Latent Content: The hidden psychological meaning (e.g., you are running away from your final exam stress). Activation-Synthesis: The brain's attempt to make sense of random neural static. The brain "synthesizes" a story from random "activation." Information Processing: Dreams help us sort out the day's events and consolidate memories. Threat Simulation Theory: Dreaming allows us to "practice" surviving dangerous situations in a safe environment. WEEK 6: Thinking and Processing This is about "Cognition"—how we use our "Pink Slime" to solve problems and make decisions. 1. Building Blocks of Thought Concepts: Mental groupings of similar objects (e.g., the concept of "Dogs"). Prototype: The best example of a category. (If I say "Bird," you probably think of a Robin, not a Penguin. The Robin is your prototype). Schemata (Schema): A mental framework that helps us organize and interpret information (e.g., your "School Schema" includes desks, teachers, and bells). 2. Problem-Solving Tactics Trial-and-Error: Trying random solutions until one works. (Slow and inefficient). Algorithms: A step-by-step, logical rule that guarantees a solution. (e.g., a math formula or checking every single aisle in a store to find milk). Heuristics: A mental shortcut or "rule of thumb." It's faster than an algorithm but can lead to errors. (e.g., looking at the signs above the aisles to find the milk). 3. The Biases (Why we make mistakes) Confirmation Bias: Searching for information that supports our preconceptions and ignoring everything else. Hindsight Bias: After an event occurs, believing we "knew it all along." Anchoring Bias: Getting "stuck" on the very first piece of information offered. (e.g., if a shirt is "on sale" for $50 down from $100, you think $50 is a deal, even if the shirt is only worth $10). Availability Heuristic: Estimating the likelihood of events based on how easily they come to mind. (e.g., being afraid of a plane crash because you saw one on the news, even though car crashes are more common). Mental Set: The tendency to approach a problem in one particular way, often a way that has worked in the past but may not work now. WEEK 7: Memory Memory is the persistence of learning over time. 1. The Three Stages of Memory Encoding: Getting information into our brain. Semantic Encoding: Encoding the meaning of words (Deepest processing). Visual Encoding: Encoding images. Acoustic Encoding: Encoding sounds. Storage: Retaining that information. Retrieval: Getting the information back out. 2. Types of Storage Short-Term Memory (STM): Holds about 7 items (plus or minus 2) for about 20 seconds. Long-Term Memory (LTM): Unlimited capacity and can last a lifetime. Explicit (Declarative): Facts and experiences (Semantic = facts; Episodic = your life stories). Implicit (Procedural): Skills (like riding a bike or typing). 3. Memory Sins & Failures Schacter’s Seven Sins: Includes Transience (fading over time), Absent-mindedness (forgetting your keys), and Persistence (unwanted memories that won't go away). Amnesia: Anterograde: You can't form new memories. Retrograde: You can't remember the past. 4. Enhancement Techniques Chunking: Organizing items into familiar, manageable units. Spaced Repetition: Studying small amounts over a long time rather than cramming. Mnemonic Devices: Memory aids like "PEMDAS" for math. 5. The "Subtle" Memory Sins (Week 7) The Serial Position Effect: You are most likely to remember the beginning of a list (Primacy Effect) and the end of a list (Recency Effect), but you’ll probably forget the middle. Pro-Tip: This is why you should study the "middle" weeks (Week 4, 5, 6) extra hard! Misinformation Effect: This is why eyewitness testimony is shaky. If someone asks, "How fast was the car going when it smashed into the pole?" you will remember the car going faster than if they said "hit." WEEK 8: Lifespan Development Developmental psychology examines how we change physically, cognitively, and socially from "womb to tomb." 1. Cognitive Development (Jean Piaget) Piaget believed children think differently than adults and move through four stages: Sensorimotor (0–2 years): Exploring the world through senses. Key milestone: Object Permanence (realizing things still exist even if you can't see them). Preoperational (2–7 years): Symbolic thought (make-believe) but lacks logic. Key trait: Egocentrism (thinking everyone sees the world exactly as they do). Concrete Operational (7–11 years): Logical thinking about physical objects. Key milestone: Conservation (understanding that volume stays the same even if the shape of the glass changes). Formal Operational (12+ years): Abstract reasoning and hypothetical "what if" thinking. 2. Psychosocial Development (Erik Erikson) Erikson focused on "crises" we face at each age. Trust vs. Mistrust (Infancy): Is the world safe? Identity vs. Role Confusion (Adolescence): "Who am I?" (This is the most common exam question). Integrity vs. Despair (Late Adulthood): Looking back on life with satisfaction or regret. 3. Moral Development (Lawrence Kohlberg) Pre-conventional: Doing the right thing to avoid punishment or get a reward. Conventional: Doing the right thing because it's the law or to fit in. Post-conventional: Doing the right thing based on universal ethical principles (even if it breaks the law). 4. Parenting Styles Authoritative: High warmth, high rules. (The "Goldilocks" style—best outcomes). Authoritarian: Low warmth, high rules. ("Because I said so!"). Permissive: High warmth, low rules. (More like a friend than a parent). Uninvolved: Low warmth, low rules. (Neglectful). WEEK 9: Learning Learning is a relatively permanent change in behavior due to experience. 1. Classical Conditioning (Ivan Pavlov) Learning by association (connecting two stimuli). Unconditioned Stimulus (UCS): The natural trigger (Food). Unconditioned Response (UCR): The natural reflex (Drooling for food). Neutral Stimulus (NS): A trigger that means nothing yet (A Bell). Conditioned Stimulus (CS): The bell after it has been paired with food. Conditioned Response (CR): Drooling for the bell alone. 2. Operant Conditioning (B.F. Skinner) Learning by consequences (Rewards and Punishments). Positive Reinforcement: Adding something good to increase behavior (A gold star for working). Negative Reinforcement: Removing something bad to increase behavior (The car stops beeping when you buckle your seatbelt). Positive Punishment: Adding something bad to stop behavior (A speeding ticket). Negative Punishment: Taking away something good to stop behavior (Taking away your phone). 3. Observational Learning (Albert Bandura) Learning by watching others. Famous study: The Bobo Doll Experiment, where kids imitated adults punching a doll. 4. The "Fine Print" of Learning (Week 9) Spontaneous Recovery: After a behavior has been "extinct" (gone away) for a while, it suddenly reappears out of nowhere. (Like Pavlov's dog suddenly drooling at a bell weeks after he stopped). Generalization vs. Discrimination: Generalization: Fearing all dogs because one bit you. Discrimination: Only fearing the specific dog that bit you. WEEK 10: Social Influences This is the study of how the "situation" and "group" overpower the individual. 1. The Stanford Prison Experiment (Zimbardo) Demonstrated the power of Social Roles and Scripts. Ordinary students became abusive "guards" or submissive "prisoners" simply because of the role they were assigned. 2. Influence & Conformity Normative Social Influence: Conforming to fit in and be liked (Dressing like your friends). Informational Social Influence: Conforming because you think the group has more info than you (Following the crowd in a new city). Obedience (Milgram): Following orders from an authority figure, even if it hurts someone else. 3. Group Dynamics Social Loafing: Working less hard in a group than when alone (The "Billy" effect). Deindividuation: Losing self-awareness and self-restraint in a large crowd or behind an anonymous screen. Group Polarization: When group discussion leads to more extreme opinions. Bystander Effect: People are less likely to help if others are around due to a Diffusion of Responsibility. 4. Thinking Patterns Fundamental Attribution Error: Blaming someone's personality for their behavior while ignoring the situation. Cognitive Dissonance: The "icky" feeling when our actions don't match our beliefs (e.g., you hate lying, but you just lied to your mom). We usually change our beliefs to match our actions to feel better. 5. Social Psych "Secret" Terms (Week 10) Self-Serving Bias: When we succeed, we take the credit ("I'm a genius"). When we fail, we blame the situation ("The test was unfair"). Foot-in-the-Door vs. Door-in-the-Face: Foot-in-the-Door: Ask for something tiny first, then the big thing. Door-in-the-Face: Ask for something HUGE (get rejected), then ask for the smaller thing you actually wanted. They are more likely to say yes because it feels like a "compromise." WEEK 11: Multiculturalism & Diversity This is the study of how culture, identity, and group values shape our behavior and how we interact with others. 1. Cultural Values Individualism: Cultures that value personal independence and "Me" goals (e.g., USA). Success is based on personal achievement. Collectivism: Cultures that value group harmony and "We" goals (e.g., Latin America, Asia). Success is based on doing what is best for the family or community. 2. Acculturation (How we adapt to new cultures) Integration: The "Best of Both Worlds." Keeping your original culture while participating in the new one. Assimilation: Giving up your original identity to fully "blend in" with the new culture. Separation: Keeping your original culture and avoiding the new one. Marginalization: Feeling like you don't belong to either culture (The "lonely" state). 3. Metaphors for Society The Melting Pot: The old idea that everyone should blend together and lose their differences to become one "American" identity. The Salad Bowl: The newer idea where cultures live together but stay distinct. You can see the "tomatoes" and the "lettuce"—everyone keeps their unique flavor. 4. Social Barriers Microaggressions: Small, daily slights or "backhanded compliments" toward marginalized groups (e.g., "You’re so articulate for someone from your neighborhood"). Prejudice vs. Discrimination: Prejudice is the thought/feeling (pre-judging), while Discrimination is the action (treating someone differently). WEEK 12: Stress & Health This is the study of how our brain's "appraisal" of the world affects our physical and mental health. 1. The Appraisal Process (Lazarus) Primary Appraisal: Judging if a stressor is a Threat (harmful) or a Challenge (potential for growth). Secondary Appraisal: Evaluating your tools. "Do I have the resources to handle this?" If yes, stress stays low. If no, panic sets in. 2. The Body’s Response (Selye’s GAS) General Adaptation Syndrome (GAS): The three stages of how your body reacts to stress: Alarm: Fight-or-Flight. Heart races, adrenaline hits. Resistance: Staying on "high alert" to cope. This is where you grind through the week. Exhaustion: Your battery dies. Your immune system crashes, and you get sick (The Cohen Cold Study). 3. Types of Stress Eustress: "Good stress." The kind that motivates you to finish a project or perform well in a game. Distress: "Bad stress." Chronic pressure that leads to burnout, fatigue, and health problems. 4. Coping Strategies Problem-Focused Coping: Attacking the problem directly. (Example: Time-Blocking your homework so it isn't overwhelming). Emotion-Focused Coping: Managing the feelings. (Example: Going to the Gym or meditating to stop feeling anxious). 5. Stress "Secret" Terms Cortisol: The primary stress hormone. Great for emergencies, but too much of it "eats" your memory and weakens your heart. Psychoneuroimmunology: The fancy word for the study of how your brain (stress) talks to your immune system. WEEK 13: Mental Wellness & The Science of Happiness The goal of this week is to identify the psychological frameworks and empirical studies that explain how humans build resilience and long-term well-being. 1. The Three Dimensions of Happiness (Module 14.5) According to the textbook, happiness is an enduring state consisting of joy and contentment. It is built through three "lives": The Pleasant Life: Attaining and savoring daily pleasures that add joy to the moment (e.g., the aroma of coffee or the feeling of sunshine). The Good Life: Identifying your unique skills and using them to enrich your life. This is where you find the state of Flow—being so "in the zone" that you lose track of time. The Meaningful Life: Using your talents and efforts in the service of the greater good or to help others, which provides a deeper sense of fulfillment than pleasure alone. 2. The Four Pillars of Well-Being (Wellness Studies) Based on Dr. Richard Davidson’s research, well-being is a "trainable skill" rather than a fixed trait. It is built on: Awareness: Noticing what your mind is doing in the present moment (meta-awareness). Connection: Cultivating kindness and healthy social relationships, which are the #1 predictor of long-term health. Insight: Having curiosity about how your own mind works and not believing every negative thought as a "fact." Purpose: Having a clear sense of direction or a "life compass" that guides your daily actions. 3. Empirical Evidence: The Creswell et al. Study (2014) This study provided scientific proof that mental training has biological effects: The Setup: An experimental design where students were randomly assigned to either a mindfulness group or an analytic control group. The Independent Variable: Brief 3-day mindfulness meditation training (25 mins/day). The Dependent Variable: Biological stress markers (Cortisol levels) and self-reported stress. The Result: The mindfulness group showed significantly lower cortisol levels, proving that meditation fosters biological resilience to stress. 4. Scientifically Proven Benefits of Gratitude Research shows that gratitude is a powerful "reset" for the nervous system: Physical: Improved sleep quality and duration; fewer reported aches and pains. Psychological: Reduces "toxic" emotions (envy, resentment) and increases mental strength. Studies of 9/11 survivors showed gratitude was a major factor in preventing PTSD. Social: Encourages "pro-social" behavior, making people more likely to form and maintain new relationships. 5. Mindfulness vs. Meditation (The State vs. The Practice) It is critical to distinguish between these two often-confused terms: Mindfulness: A state of being. It is the quality of being fully present, aware of where we are and what we’re doing, without being overly reactive or overwhelmed. Meditation: The formal practice or "mental gym" used to train the brain. It is the intentional time set aside to practice techniques that eventually lead to a consistent state of mindfulness. 6. Key Terminology & Cognitive Traps Affective Forecasting: The human tendency to overestimate how much future events (both good and bad) will affect our long-term happiness. We assume milestones like "perfect grades" will provide permanent joy, but they usually don't. Optimism & Resilience: Optimism is the general tendency to expect good outcomes. It is the "engine" of resilience—the ability to "bounce back" from major life stressors (like those listed on the SRRS). Problem-Focused vs. Emotion-Focused Coping: * Problem-Focused: Dealing with the stressor directly (e.g., studying for the test). Emotion-Focused: Managing the feelings associated with the stressor (e.g., taking a nap or exercising)

MMiPeople Francesco Redi: scientist who tested spontaneous generation with rotting meat and maggot formation with an open container, sealed container, and gauze-covered container, and refuted spontaneous generation Needham: scientist who tested spontaneous generation with boiling chicken broth, sealing the container, and waiting a few days to assess for microbial growth, and supported spontaneous generation Spallanzani: scientist who tested spontaneous generation with further testing, Needham’s experiment, and tested with an open and closed container that was later opened, and refuted spontaneous generation Louis Pasteur: scientist who used swan-neck flasks in his experiment and definitively refuted spontaneous generation Anthony van Leeuwenhoek: scientist who was the first to observe eukaryotic microbes, calling them “wee animalcule” Robert Hooke: coined the term “cell” when looking at cork Matthias Schleiden: observed cells in plant tissue Theodor Schwann: observed cells in animal tissue Rudolf Virchow and Robert Remark: observed cells dividing to make new cells (not mitosis) Hippocrates: suggested disease has natural causes Thucydides: advocated for evidence-based analysis of cause and effect and suggested immunity after observing plague survivors didn't get sick again Marcus Terentius Varro: the first to propose that things we cannot see cause disease Ignaz Semmelweis: physician who observed the spread of disease among patients in different sides of the hospital and instituted hand washing between patients to reduce the spread of disease from patient to patient via healthcare workers Joseph Lister: surgeon who observed post-surgical infection and instituted hand washing and sterilization of medical equipment with 5% phenol solution for less disease Robert Koch: scientist who developed Koch’s postulates to determine the cause of disease and had a rivalry with Louis Pasteur John Snow: questioned the London cholera outbreak and asked questions to the people who had been infected about where they had been and what they had eaten or drank, and noticed that everyone who had cholera used one of two water pumps Classification of microbes What are the 2 domains that are composed of all microbes? Bacteria and Archaea What domain of life is composed only of some microbes? Eukarya What types of microbes do not fit into the domains of life? Viruses and Prions Prions: unicellular organisms in the domains Bacteria and Archaea with no nucleus and have cell walls Viruses: acellular and domainless (not alive) Eukaryotes: unicellular OR multicellular organisms, in domain Eukarya, have a nucleus, have membrane-bound organelles, and include fungi, algae, protazoa, and helminths How many times bigger are bacteria than viruses? 100x A cell is around how many times bigger than an individual bacteria? 10x Cell structures Know the function, general location, and whether they are shared with eukaryotes (if yes similarities/differences) of the following structures: 1. Nucleoid: contains chromosome(s) and nuclear-associated proteins that are usually haploid and circular near the center of the cell, which hold the DNA genetic information without a membrane Eukaryotes = have a nucleus, are diploid and linear Prokaryotes = have nucleoid, are haploid and circular 2. Ribosomes: work with mRNA protein synthesis, made up of proteins and RNA, found in cytoplasm Eukaryotes: 80S, 60 large, 40 small (18S sequencing) Prokaryotes: 70S, 50 large, 30 small (16S sequencing) 3. Cytoplasm: fluid inner layer 4. Fimbriae: short, bristle-like projections for attachment to surfaces 5. Endospores: not all bacteria have, protect bacteria in a dormant state/ harsh environment, found inside bacteria, sporulation = the process of becoming dormant, germination = process of becoming active 6. Plasma membrane: semipermeable, composed of lipids and proteins, controls transport into and out of cell, most inner layer before cytoplasm (ex: facilitated diffusion, active transport, diffusion, endocytosis (Eukaryotes), sterols (Eukaryotes), and cholesterol (Eukaryotes) Same for Eukaryotes 7. Cell wall: protects against harsh changing environments and osmotic stress, contains peptidoglycan in bacteria, contains Gram + and Gram - Steps of Gram stain: dye with crystal violet, iodine (mordant), alcohol (decolorizer), and safranin red If mycobacteria complete an acid-fast stain Gram + has LTA an TA and one membrane Gram - has LPS and 2 membranes 8. Capsule: protective protein shell, outermost layer 9. Pilus: medium projection, adheres to surfaces, does DNA gene transfer 10. Flagellum: long protein projections made of flagellin for movement (ex: 1= monotrichous, one at each end = amphitrichous, many at one end = lophotrichous, many flagella all over the cell = peritrichous 11. Plasmid: circular, double-stranded DNA not part of the chromosome, and can have 1-100 of the same or different plasmids to help with gene transfer, antibiotic resistance, and virulence factors, found anywhere in the cytoplasm Not part of Eukaryotes 12. Inclusion: not all bacteria have, helps with the storage of nutrients and other materials, has protein shell, and is found in cytoplasm (ex: lipid droplets store fats, volutin stores inorganic phosphates, sulfur inclusions store sulfur, gas bubbles store gas for buoyancy in water, magnetosomes store metals for movement) Not part of Eukaryotes; instead, they have vesicles for storage All cellular microbes have what four (4) components? Cell Membrane, Cytoplasm, Ribosomes, and DNA What is the only component of all cells that viruses have? Cytoplasm Know/ be able to identify the shapes of bacteria Round shape: coccus Rod shape: bacillus Vibrio: curved rod shape Short rods with combo of coccus and bacillus: coccobacillus Wavy spiral shape: Spirillum Coiled spiral shape: Spirochete Microbial growth Phases of growth Lag Phase: bacteria gear up for replication by increasing cell size, metabolism, and protein synthesis Log Phase: exponential growth phase, where bacteria actively replicate and are most susceptible to antibiotics Stationary Phase: growth curve flatlines bc bacteria are dying at same rate of growth, begin survival mode and sporulation, produce secondary metabolites, and produce virulence factors, and are low on space, nutrients, and oxygen Death Phase: bacteria die at exponential rate, increase amount of toxic waste, release spores, some spontaneously lyse to feed others, and persister cells refuse to die How do microbes replicate? Through binary fission, fragmentation, budding, and sexually What is a biofilm? Communities of bacteria (steps: colonization, attachment, replication, make EPS with antibiotic resistance, EPS kick bacteria out to replicate somewhere else) How does quorum sensing work? Bacteria want to work together, so they secrete autoinducers, and when you activate enough receptors, they activate a response Growth requirements – classifications and adaptations 1. Oxygen requirements Obligate Aerobes: need O2 to survive Obligate Anaerobes: die in presence of O2 Faculative: mostly need O2 but can survive without it Microaerophiles: need O2 for survival but not atmospheric O2 (low levels) Aerotolerant: can survive with or without oxygen Capnophiles: like high CO2 and low O2 2. pH requirements Acidophiles: low pH (2-4), high H+ environments, efflux pumps to remove H+ ions, changes membrane composition to withstand low pH Neutrophiles: neutral pH (7), found within body Alkaliphiles: basic pH (9-10), modified lipid protein structures, modified electron transport system that use Na+ instead of H+, high OH- environment 3. temperature requirements Psychrophiles: like freezing temperatures a below 0-15 degrees, die at or above 20 degrees, found in cold lakes or the ocean floor, have hydrophobic proteins to increase flexibility, have decreased secondary stabilizing bonds Psychrotolerant: cold not ideal but wont kill them, live between 4-25 degrees (fridge temperature) Mesophiles: moderate temperatures, 20-40 degrees, grow in body Thermophiles: hot environments 50-80 degrees, hot springs, geothermal soil Hyperthermophiles: very hot environments 80-110 degrees, found in hydrothermal vents, increased saturation in membranes, increased stabilizing bonds, alter amino acids to prevent denaturation 4. osmolarity requirements Hypertonic: more water out Hypotonic: more water in Isotonic: equal water in and out Halotolerant: dont require salt but can grow in high salt environments Halophiles: love salt, found in ocean and salt lakes, have increased cytoplasmic glycerol, have efflux pumps for salt 5. barometric requirements Barophile: survive high atmospheric environments like the bottom of the ocean (something at top of mountain has low atmospheric pressure) Microbial Metabolism Means of generating energy (do the processes require oxygen?, which gives the most energy?) Glycolysis: does not require O2 bc it can be used during fermentation, used 2 ATP, makes 4 ATP, NET 2 ATP Kreb’s cycle: requires O2; NET after 1 round= 1ATP, 1 NADH, 1FADH2 (x2 for second round) Electron transport: requires O2, biggest payout of ATP with NET 34 ATP Photosynthesis: does not require O2 as it is a waste product, can do oxygenic and anoxygenic Microbial genetics DNA Replication – enzymes and functions DNA gyrase: unwinds DNA (enzyme) Helicase: unzips DNA (enzyme) Single-stranded binding proteins: bind to DNA so doesnt close back up (protein) Single-stranded binding proteins: bind to DNA so doesnt close back up (protein) DNA polymerase III: lay down new DNA nucleotides, synthesizes leading and lagging strands 5’ →3’(enzyme) DNA polymerase I: removes RNA primers (enzyme) DNA Ligase: seals RNA primers (enzyme) Topoisomerase 4: separates 2 circular chromosomes Transcription and translation – enzymes and function 1. RNA polymerase: turns DNA→ mRNA (transcription) 2. Ribosomes: 30S small, 50S large, 70S total 3. tRNA: A,P, and E sites, bacteria links transcription and translation bc no nucleus, has anticodon at opposite long 3’ end, high energy bond, same active translation process as Eukaryotes Be able to do DNA base pairing, transcription, and translation (given codon table) Also know differences between prokaryotic and eukaryotic Replication, transcription, and translation Genetic Diversity – how does this work? 1. Transformation: uptake of plasmid into different bacteria and is incorporated into its genetic material 2. Transduction: bacteriophage inserts its plasmid into a bacteria (virus that infects a bacteria) 3. Conjugation: like plasmid transfer (ex: rolling circle replication), “bacterial sex” 4
