Question

Quizplus · Accepted Answer

Molecular oxygen acts as the final electron acceptor in the electron transport chain and is reduced when it accepts electrons to form water. Option A is incorrect because molecular oxygen is reduced, not oxidized. Option B is incorrect because the transfer of electrons from one carrier to another releases small amounts of energy, not large amounts. Option D is incorrect because electrons move from carriers that have less affinity for them to carriers that have more affinity for them.
