Each protein in an electron transport chain is sequentially oxidized,then reduced,allowing the work of actively transporting oxygen molecules by active membrane transport.

Question

Quizplus · Accepted Answer

The primary function of the electron transport chain is to facilitate the transfer of electrons from electron donors to electron acceptors, not to transport oxygen molecules by active membrane transport. Oxygen acts as a final electron acceptor to form water, but the proteins themselves are involved in electron transfer, not active transport of oxygen.
