Which of the following statements accurately describes a difference between fermentation and cellular respiration?
A: Fermentation produces significantly more ATP per glucose molecule than cellular respiration.
B: In fermentation, NADH is regenerated to NAD+ by transferring electrons to an organic molecule, while in cellular respiration, it's transferred to an electron transport chain.
C: Both fermentation and cellular respiration require oxygen as the final electron acceptor.
D: Cellular respiration occurs entirely in the cytosol, while fermentation occurs in the mitochondrion.
Explanation
The text states that in fermentation, the final electron acceptor is an organic molecule such as pyruvate or acetaldehyde, which regenerates NAD+. In cellular respiration, electrons are transferred to an electron transport chain, which regenerates NAD+. This is a fundamental distinction.
