Detailed explanation-1: -In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt. If enough oxygen is not present to undergo aerobic respiration, pyruvate will undergo lactic acid fermentation.
Detailed explanation-2: -Explanation: Aerobic respiration requires oxygen. In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.
Detailed explanation-3: -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-4: -In the absence of oxygen, NAD+ may not be regenerated via the electron transport chain (which depends on oxygen as the terminal electron acceptor). Fermentation allows NAD+ to be regenerated in the absence of oxygen via lactic acid fermentation or alcohol fermentation.
Detailed explanation-5: -“Fermentation is an anaerobic process in which energy can be released from glucose even if oxygen is not available.”
