Quizplus · Accepted Answer

The electron carriers along the electron transport chain alternate between being reduced (gaining electrons) and being oxidized (losing electrons), which allows for the transfer of electrons down the chain. Chemiosmosis and ATP generation occur due to a proton gradient established by the movement of electrons. The energy of the electrons decreases as they move down the chain, as they are used to drive proton pumping and ATP synthesis. Therefore, choices A, C, D, and E are all incorrect.
