Detailed explanation-1: -Lactic acid fermentation happens in the skeletal muscles. Pyruvate is converted to lactic acid by lactate dehydrogenase when oxygen is inadequate. Fatigue is brought on by lactic acid buildup in the muscles. It is a sort of anaerobic fermentation that takes place in bacterial and animal cells, such as muscle cells.

Detailed explanation-2: -Lactic acid fermentation is the process by which our muscle cells deal with pyruvate during anaerobic respiration. This happens when we exercise too fast or hard because the oxygen supply can’t keep up with the need. That’s when our muscles switch from aerobic respiration to lactic acid fermentation.

Detailed explanation-3: -Fermentation usually happens in yeast cells and bacteria. Also, the animal muscle cells show lactic acid fermentation in case of inadequate oxygen supply. In yeast, there is incomplete oxidation of glucose that happens in an anaerobic environment. Here, pyruvic acid is converted into carbon dioxide and ethanol.

Detailed explanation-4: -Human muscle cells also use fermentation. This occurs when muscle cells cannot get oxygen fast enough to meet their energy needs through aerobic respiration. There are two types of fermentation: lactic acid fermentation and alcoholic fermentation.
