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: -Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.
Detailed explanation-3: -In the absence of oxygen, oxidative phosphorylation cannot be used to produce ATP, so glycolysis becomes the primary source of ATP for the cell. The importance of lactic acid fermentation is that it replenishes cellular for the glyceraldehyde-3-phosphate dehydrogenase reaction, which precedes the ATP-producing steps.
