Question

Quizplus · Accepted Answer

An electron transfer chain involves the stepwise transfer of electrons from one compound to another, resulting in the generation of energy. This process occurs in the mitochondria of eukaryotic cells during cellular respiration, where electrons are transferred from electron donors (such as NADH) to electron acceptors (such as oxygen), ultimately producing ATP.
