Detailed explanation-1: -Muscle cells opt for lactic acid fermentation due to less availability of oxygen. In this process they produce lactic acid and less energy per glucose molecule.

Detailed explanation-2: -Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In yeast cells (the yeast used for baking bread and producing alcoholic beverages), glucose can be metabolized through cellular respiration as in other cells.

Detailed explanation-3: -In muscle cells, fermentation occurs through the lactic acid pathway. During this process, glucose is phosphorylated, broken down and oxidised to make two molecules of pyruvate. The produced pyruvate is then reduced by NADH to make lactic acid. Only two ATP molecules are produced using this pathway.

Detailed explanation-4: -Fermentation is an anaerobic process in which energy is produced from glucose in absence of oxygen. It takes place in yeast, bacteria, plants and in the muscle cells of animals.
