Which of the following is not part of the process known as oxidative phosphorylation?
(a) Molecular oxygen serves as a final electron acceptor.
(b) FADH2 and NADH become oxidized as they transfer a pair of electrons to the electron-transport chain.
(c) The electron carriers in the electron-transport chain toggle between reduced and oxidized states as electrons are passed along.
(d) ATP molecules are produced in the cytosol as glucose is converted into pyruvate.
(d) During glycolysis, ATP generation occurs simultaneously with two of the key reactions that convert glucose to pyruvate in the cytosol. This production of ATP in the absence of oxygen is not part of oxidative phosphorylation; it is referred to as substrate-level phosphorylation.
