Transfer of NADH from glycolysis into the mitochondria

WebNADH is not oxidized by the electron transport chain (i.e., the oxidative phosphorylation does not occur) in the absence of aerobic or anaerobic respiration because, in that … 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. WebRegeneration of NAD Regeneration of NAD It is thus able to reduce other compounds by passing on the hydrogen as hydrogen ions (protons) and electrons.

WebHow is NADH 2 regenerated to NAD in mitochondria (2 pts)? a. What does this pathway yield (2 pts)? 9. Because NADH 2 that is made in the cytosol can’t be transported across the mitochondrial membrane to be oxidized to NAD +, the body has developed 2 ways to transport the reducing equivalents (H + ions) into the mitochondria. a. WebProcesses that use an organic molecule to regenerate NAD + from NADH are collectively referred to as fermentation. In contrast, some living systems use an inorganic molecule as a final electron acceptor; both methods are a type of anaerobic cellular respiration. Anaerobic respiration enables organisms to convert energy for their use in the ...
