Detailed explanation-1: -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-2: -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-3: -During decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients.

Detailed explanation-4: -Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. This process of breaking down glucose in the absence of oxygen is aptly named anaerobic glycolysis.[1]

Detailed explanation-5: -Cellular respiration is a metabolic pathway that uses glucose to produce adenosine triphosphate (ATP), an organic compound the body can use for energy.
