A total of four ATP molecules have to be used by aerobic respiration in eukaryotic cells.Where are these four ATP molecules used?

Question

Quizplus · Accepted Answer

Two ATP molecules are used to start glycolysis. During the process of glycolysis, four ATP molecules are produced, but two are used up during the process, so the net production of ATP during glycolysis is two. Two NADH molecules are also produced during glycolysis, which are then transported into the mitochondria. Each NADH molecule can produce up to three ATP molecules through the electron transport chain, which requires two ATP molecules to move the NADH molecules into the mitochondria. Therefore, a total of four ATP molecules are used to move the two NADH molecules from glycolysis into the mitochondria, which is where they will be used to generate additional ATP molecules via oxidative phosphorylation.
