Question

Quizplus · Accepted Answer

During the Krebs cycle, all of the processes mentioned in the answer choices occur. Substrate-level phosphorylation results in the production of ATP, oxaloacetate is regenerated to restart the cycle, electrons and H+ ions are transferred to the coenzymes NAD+ and FAD to carry them to the electron transport chain for oxidative phosphorylation, and molecules of carbon dioxide are produced as a waste product.
