Which of the following metabolic pathways involves the transport of electron and H⁺ ions and the subsequent synthesis of ATP molecules?

Question

Quizplus · Accepted Answer

The oxidative phosphorylation pathway involves the transport of electrons and H+ ions across the inner mitochondrial membrane, which creates a proton gradient that is used to synthesize ATP. The citric acid cycle does not involve the transport of electrons and H+ ions, but rather the generation of high-energy molecules (e.g. NADH, FADH2) that are then used in oxidative phosphorylation. Therefore, only choice A (the oxidative phosphorylation pathway) is correct.
