Quizplus · Accepted Answer

All of the answer choices are correct. A proton gradient is required to create a charge imbalance across the inner mitochondrial membrane, which drives the production of ATP by ATP synthase. The oxidation of electron carrier molecules, such as NADH and FADH2, releases energy that is used to pump protons across the inner mitochondrial membrane, creating the proton gradient. Oxygen is the final electron acceptor in the electron transport chain, and its reduction creates water. Movement of electrons through proteins in the electron transport chain is the mechanism by which energy is released and used to pump protons.
