These are the processes which involved in the regeneration of the NAD+ pools

Fermentation: The metabolic process by which the organic compounds like glucose degraded into products like alcohol or organic acids in the absence of oxygen is called fermentation. In skeletal muscles, there is high demand for energy so it depends upon the anaerobic glycolysis. In the anaerobic glycolysis, the glucose degraded into pyruvate which is later on converted to lactic acid by the lactate dehydrogenase which results in the generation of two NAD+ molecules from the NADH2.

Anaerobic respiration: A series of metabolic steps used to extract the energy from the organic molecules like glucose is called cellular respiration. If the cellular respiration occurs in the absence of oxygen, it is called anaerobic cellular respiration. Lactic acid and alcoholic fermentation types of anaerobic respiration which involves generation of NAD+ molecules from the NADH2.

Aerobic respiration: occurrence of cellular respiration in the presence of oxygen is called aerobic cellular respiration. The NADH2 generated in glycolysis & Kreb’s cycle enters into the electron transport chain oxidized into the NAD+.

Electron transport chain: located in the inner mitochondrial membrane with four protein complexes which carry electrons from the NADH2 to terminal oxygen and produces the NAD+.
