WebThis energy is derived from the oxidation of NADH and FADH2 by the four protein complexes of the electron transport chain (ETC). The ten NADH that enter the electron transport originate from each of the earlier processes … WebThus, NADH must be continuously oxidized back into NAD + in order to keep this step going. If NAD + is not available, the second half of glycolysis slows down or stops. If oxygen is available in the system, the NADH will be oxidized readily, though indirectly, and the high-energy electrons from the hydrogen released in this process will be used to produce ATP.

Web29 okt. 2024 · On the other hand, during aerobic respiration, NADH generated by glycolysis is oxidized to form NAD+ by the donation of its electrons to reduce pyruvate to lactate. Subsequently, NAD+ is reused in glycolysis (again) in order to generate more molecules of ATP.
