Detailed explanation-1: -Fermentation is the metabolic process where glucose is broken down in the absence of oxygen to release products like lactic acid or alcohol.

Detailed explanation-2: -When oxygen is not present or if an organism is not able to undergo aerobic respiration, pyruvate will undergo a process called fermentation. Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.

Detailed explanation-3: -There are two types of fermentation, alcoholic and lactic acid. Fermentation follows glycolysis in the absence of oxygen.

Detailed explanation-4: -Aerobic fermentation occurs in the presence of oxygen. It usually occurs at the beginning of the fermentation process. Aerobic fermentation is usually a shorter and more intense process than anaerobic fermentation.

Detailed explanation-5: -Process of anaerobic respiration But when, as in the case of fermentation, oxygen is absent, the last two stages are bypassed. Instead, pyruvate is converted into a different byproduct, and carbon dioxide is released as well.
