What is energy?
The ability to do work
What is thermodynamics?
The study of energy
what does the first law of thermodynamics state?
Energy cannot be created or destroyed, but it can be converted to another form
What does the second law of thermodynamics state?
If energy is converted, there will be a loss of usable energy
What is the difference between the first and second law?
The first law states that energy can be converted meanwhile, the second law state if converted, it will decrease the usage of energy
Where does almost all of the energy for life come from?
The sun
Where do most autotrophs get their own food from?
The sun
Where do heterotroph get their food from?
By ingesting
What is metabolism?
All of the chemical reactions in a cell
Catabolic
Pathways that Release energy
Anabolic
Pathways that use energy
Is photosynthesis anabolic or catabolic?
Anabolic
What is photosynthesis?
A anabolic pathway in which light energy from the sun is converted to chemical energy
Is cellular respiration, catabolic or anabolic?
Catobolic
What is cellular respiration?
A catabolic pathway in which organic molecules are broken down to release energy
What is ATP?
Adenosine triphosphate
how is ATP created?
It is created by using sugar during cellular respiration
When does ATP release energy?
ATP releases energy when the bonds between his atoms are broken
What do most autotrophs make sugar from?
Photosynthesis
What does photosynthesis convert sunlight to?
Carbohydrates (Sugar)
What two phases does photosynthesis occur
Light dependent phase and light independent phase
What is light dependent phase?
Light energy is captured, but only during the day
What is light independent phase?
Molecules are then used to make glucose (sugar) Which can happen day or night
What are chloroplast?
Organelles that capture light Energy
What are the two main parts of chloroplast?
Thylakoids and stoma
What are thylakoids?
Flatten sac-like membranes
What is a grana
Stacked of thylakoids
What is a stoma?
Fluid filled space outside the grana
What is a pigment?
Color substances that absorb or reflect light
What is the color I see?
The color I see is the color reflected, not absorbed
What is the important pigment in photosynthesis?
Chlorophyll
Where is chlorophyll found?
In the chloroplast of plant cells
What colors do chlorophyll’s absorb?
Chlorophyll’s observed, red and blue out of red and blue and green
What happens during digestion?
Stored chemical energy is transferred to other organisms
What do heterotrophs use?
Stored energy by breaking apart large molecules during digestion
What does digestion create?
Glucose and other molecules
What does photosynthesis create?
Sugar and oxygen only
Where do organisms obtain their energy from?
Cellular respiration
True or false the equation for cellular respiration is the same as photosynthesis
False it is the opposite
How many parts are there in cellular respiration?
Two
Cellular respiration has what two parts
Glycolysis and kerbs cycle
What is the glycolysis cycle?
A anaerobic process that requires no oxygen
What is the kerbs cycle and electron transport chain
A aerobic process requiring oxygen
Where does cellular respiration mostly occur in?
The mitochondria
Where does a glycolysis occur?
The cytoplasm
How many ATP do you get from the glycolysis process?
2 ATP’s from one molecule of sugar
How many carbon molecules are left over in the glycolysis process
Two extra carbon molecules
Where does the Krebs cycle take place?
The mitochondria
How many carbon molecules does the kerbs cycle use?
Two extra carbon molecules
What does the krebs cycle release?
CO2
How many ATP‘s are created in the Krebs cycle
Two
True or false several other molecules are made in the krebs cycle
True true
Where does the electron transport take place in?
Mitochondria
How many times does a electron transport run?
Several times
How many ATP’s are created in the electron transport
32
What is released in the electron transport?
Water and CO2
What is a net gain in the glycolysis process?
2 ATP
What is the net gain in the krebs cycle?
2 ATP
What is the net gain in electronic transport chain?
32. ATP.
What is the total amount of ATP that comes from one sugar molecule?
36. ATP.
What is anaerobic respiration?
When oxygen is unavailable cells can’t do krebs cycle or ETC
What is fermentation?
The anaerobic process that follows glycolysis
Where does fermentation occur and what does it produce?
Fermentation occurs in the cytoplasm and produces ATP without oxygen
What is lactic acid fermentation
When compounds are converted into lactic acid
When do muscles produce lactic acid?
Muscles produce lactic acid when not enough oxygen
What is alcohol fermentation?
A process that occurs in yeast and some bacteria
What does alcohol fermentation make
Makes ethyl alcohol and carbon dioxide
