What is the immediate source of the energy used to synthesize ATP by oxidative phosphorylation in eukaryotic cells? A)oxidation of glucose to CO₂ and water B)the thermodynamically favorable flow of electrons from NADH to proteins associated with the mitochondrial electron transport chain C)the transfer of protons and electrons to oxygen D)the proton-motive force across the inner mitochondrial membrane E)the thermodynamically favorable transfer of high-energy phosphate groups from molecules in glycolysis and the citric acid cycle to ADP

Question

Quizplus · Accepted Answer

The immediate source of energy for ATP synthesis by oxidative phosphorylation in eukaryotic cells is the proton-motive force across the inner mitochondrial membrane. This force is generated by the electron transport chain and drives the synthesis of ATP from ADP and inorganic phosphate by ATP synthase.
