PracticeQ: Cellular Respiration + Fermentation

What is the difference between cellular respiration and photosynthesis? inputs and outputs

Photosynthesis uses energy from the sun, CO2 and H2O to make glucose and O2.

Cellular respiration uses the products of photosynthesis to create energy with the waste products of CO2 and H2O

Name one difference between heterotrophs and autotrophs AND give one example of a different type of organism for each.

autotrophs: stores energy from sun or other inorganic source, makes own food, producers, self feeders, create organic matter from inorganic nutrients

plant, algae, certain protists or certain bacterial examples

 

heterotrophs: need to eat, other-feeders, consumers, cannot make organic molecules from inorganic ones.

animals, fungi, some bacteria

T/F: In the mitochondrial inheritance, a child only receives mitochondria from their mother, NOT their father.

True

If someone becomes more active and continues to stay active the number of mitochondria in their cells will:

increase

Accounts for the most of ATP synthesis in CR

oxidative phosphorylatioin

breaks down glucose into pyruvates in CR

glycolysis

completes the breakdown of glucose in CR

citric acid cycle

glycolysis location

cytoplasm

citric acid cycle location

mitochondrial matrix

oxidation phosphorylation location

cristae (inner membrane of the mitochondria)

What are the outputs of the Citric Acid Cycle? (2 turns of the CAC to process a full Glucose molecule)

4 CO2, 2 ATP, 6 NADH, 2 FADH2

what are the waste products of cellular respiration

CO2 and H20

How many ATPs does the Citric Acid Cycle produce directly? (From 1 starting Glucose)

2

How many ATP does glycolysis produce directly (from 1 starting glucose)

2

T/F: reduction is the loss of electrons while oxidation is the acceptance of electrons

False

T/F: During cellular respiration, oxygen is oxidized and glucose is reduced

false

What two molecules supply electrons to the Electron Transport Chain

NADH and FADH2

Most of the ATP in the cell are made during which stage of cellular respiration?

oxidative phosphorylation

T/F: ATP synthase uses the protein gradient across the inner mitochondrial membrane to turn ATP into ADP by removing one phosphate group.

False

T/F: The electron transport chain uses energy from electrons to pump Hydrogen from the intermembrane space into the matrix.

false

What are the outputs of alcohol fermentation (excluding those from glycolysis and those recycled into glycolysis)

 

2 CO2 and 2 Ethanol

What are the outputs of Lactic Acid fermentation (excluding those from glycolysis and those recycled into glycolysis)

2 lactate

What is the chemical equation of cellular respiration?

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP

Name the molecule above, and name the 3 different components that make up the molecule

ATP, or adenosine triphosphate

 

1. Adenosine molecule

2. Ribose Sugar

3. Three phosphate groups
