Which of the following processes involves the use of an organic compound as an electron acceptor?
Correct answer: C. Fermentation
- A. Aerobic respiration
- B. Anaerobic respiration
- C. Fermentation
- D. Glycolysis
Explanation
In fermentation, which occurs in the absence of an external electron acceptor like oxygen, an organic molecule (such as pyruvate or acetaldehyde) generated during glycolysis is used as the final electron acceptor. This regenerates the NAD+ needed for glycolysis to continue.
