- ATP NAD+ FADH2 Coenzyme A ATP synthase oxidizing agent in metabolism enzyme "motor" located on the inner membrane of mitochondrial works with CoQ10 in oxidative phosphorylation shuttles electrons in the e- transport chain provides energy to drive an endergonic reaction forward shuttles two-carbon units (acetyl groups) reducing agent in metabolism turns pyruvate to lactate in anaerobic conditionsarrow_forwardFADH2 is a less powerful reducing agent (electron donor) than NADH. What is the consequence of this in oxidative phosphorylation? FADH, requires more steps than NADH does in electron transport to become oxidized. The electrons from FADH2 enter electron transport at a higher energy level than the electrons from NADH. A molecule of FADH, is only capable of producing 2 molecules of ATP, while a molecule of NADH is capable of producing 3 molecules of ATP. Oxidation of FADH, occurs in the cytoplasm of the cell, while oxidation of NADH occurs in the mitochondria. FADH, can only donate 1 phosphate group to ATP, while NADH can donate 2 phosphate groups to ATP.arrow_forwardIn complex III in the electron transport chain electrons from NADH + H+ are transferred to coenzyme Q.
