Fermentation & Anaerobic Respiration
Multiple Choice
Which statement about anaerobic respiration is true?
A
Anaerobic respiration produces more ATP per glucose molecule than aerobic respiration.
B
Anaerobic respiration uses water as the final electron acceptor.
C
Anaerobic respiration occurs only in plant cells.
D
Anaerobic respiration does not require oxygen to generate ATP.
Verified step by step guidance1
Understand the concept of anaerobic respiration: Anaerobic respiration is a type of cellular respiration that occurs in the absence of oxygen. It allows cells to generate ATP without relying on oxygen as the final electron acceptor.
Compare anaerobic respiration to aerobic respiration: Aerobic respiration produces significantly more ATP per glucose molecule (approximately 36-38 ATP) compared to anaerobic respiration, which typically produces only 2 ATP per glucose molecule.
Identify the final electron acceptor in anaerobic respiration: Unlike aerobic respiration, which uses oxygen as the final electron acceptor, anaerobic respiration uses other molecules, such as pyruvate or nitrate, depending on the organism and pathway.
Clarify the occurrence of anaerobic respiration: Anaerobic respiration is not limited to plant cells; it occurs in various organisms, including bacteria, yeast, and animal cells under low oxygen conditions (e.g., during intense exercise).
Confirm the correct statement: The defining characteristic of anaerobic respiration is that it does not require oxygen to generate ATP, making the statement 'Anaerobic respiration does not require oxygen to generate ATP' true.
