Which of the following would not be used as a final electron acceptor in anaerobic respiration?

Question

Quizplus · Accepted Answer

Anaerobic respiration occurs in the absence of oxygen, so oxygen cannot be used as a final electron acceptor in this type of respiration. Instead, other molecules such as sulfur, iron, or nitrogen may serve as the final electron acceptor in various anaerobic respiratory pathways. Protons, on the other hand, are not molecules that can act as electron acceptors, but rather are involved in creating an electrochemical gradient that drives ATP synthesis in both aerobic and anaerobic respiration.
