Detailed explanation-1: -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-2: -Lactic acid, also known as lactate, is a substance the body produces mainly by the breakdown of glucose under anaerobic conditions (i.e., without oxygen), like anaerobic glycolysis.
Detailed explanation-3: -4: Lactic acid fermentation makes ATP in the absence of oxygen by converting glucose to lactic acid (through a pyruvate intermediate). Making lactic acid from pyruvate oxidizes NADH, regenerating NAD+ so that glycolysis can continue to make more ATP rapidly.
