Aerobic Respiration Flashcards
What is aerobic respiration?
A metabolic process that uses oxygen to convert glucose into energy.
True or False: Aerobic respiration occurs in the mitochondria of cells.
True
What are the main products of aerobic respiration?
Carbon dioxide, water, and ATP (adenosine triphosphate).
Fill in the blank: The equation for aerobic respiration is C6H12O6 + ___ → 6CO2 + 6H2O + ATP.
6O2
Which process precedes aerobic respiration?
Glycolysis.
What is the net gain of ATP from glycolysis?
2 ATP molecules.
What is the role of oxygen in aerobic respiration?
Oxygen acts as the final electron acceptor in the electron transport chain.
True or False: Lactic acid is produced during aerobic respiration.
False
What is the main energy currency produced during aerobic respiration?
ATP (adenosine triphosphate).
Where does the Krebs cycle occur?
In the mitochondria.
What are the two main stages of aerobic respiration?
The Krebs cycle and the electron transport chain.
Multiple Choice: Which of the following is NOT a step in aerobic respiration? A) Glycolysis B) Fermentation C) Krebs Cycle D) Electron Transport Chain
B) Fermentation
What is produced during the Krebs cycle?
NADH, FADH2, ATP, and carbon dioxide.
Fill in the blank: The electron transport chain uses ___ to generate ATP.
NADH and FADH2
True or False: Aerobic respiration is more efficient than anaerobic respiration.
True
What is the total ATP yield from one molecule of glucose during aerobic respiration?
Approximately 36 to 38 ATP molecules.
What is oxidative phosphorylation?
The process of ATP production in the electron transport chain coupled with the reduction of oxygen.
Multiple Choice: Which of the following is a byproduct of aerobic respiration? A) Ethanol B) Oxygen C) Carbon Dioxide D) Glucose
C) Carbon Dioxide
What happens to the electrons during aerobic respiration?
They are transferred through a series of proteins in the electron transport chain.
Fill in the blank: The primary purpose of aerobic respiration is to convert ___ into energy.
glucose
Where does glycolysis occur?
In the cytoplasm of the cell.
What is the significance of the proton gradient in aerobic respiration?
It drives the synthesis of ATP via ATP synthase.
True or False: Aerobic respiration can occur without oxygen.
False
What is the role of ATP synthase in aerobic respiration?
It synthesizes ATP from ADP and inorganic phosphate using the energy from the proton gradient.
