Which of the following statements concerning oxidative phosphorylation is false? Group of answer choices: The electron transport chain generates an electrochemical gradient that drives the production of ATP. ATP synthase with fewer subunits in its c ring will produce more ATP per proton. A “loose” β subunit of ATP synthase becomes a “tight” site as it produces ATP. When the supply of NADH and QH2 (ubiquinol) decreases, ATP synthase produces more ATP.
