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: -Anaerobic respiration is a type of cellular respiration where respiration takes place in the absence of oxygen. Fermentation is an anaerobic pathway-a common pathway in the majority of prokaryotes and unicellular eukaryotes. In this process, glucose is partially oxidised to form acids and alcohol.

Detailed explanation-3: -5.2. Anaerobic fermentation occurs in the fermentation vessel once the oxygen is discharged and replaced with N2, CO2, or another by-product of the fermentation process. Anaerobic fermentation is usually a slower process.

Detailed explanation-4: -Fermentation happens in anaerobic conditions (i.e., without oxygen). Fermentation begins with glycolysis which breaks down glucose into two pyruvate molecules and produces two ATP (net) and two NADH. Fermentation allows glucose to be continuously broken down to make ATP due to the recycling of NADH to NAD+.
