MUSCLE PHYSIOLOGY

Detailed explanation-1: -Fermentation is another anaerobic (non-oxygen-requiring) pathway for breaking down glucose, one that’s performed by many types of organisms and cells. In fermentation, the only energy extraction pathway is glycolysis, with one or two extra reactions tacked on at the end.

Detailed explanation-2: -Fermentation is a type of anaerobic respiration that produces ATP. Lactic acid fermentation produces lactic acid and NAD+. Alcoholic fermentation produces ethanol and NAD+.

Detailed explanation-3: -Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.
