Detailed explanation-1: -During anaerobic respiration, lactic acid is produced. This happens when the demand for energy is more and supply of oxygen is less, mainly during heavy exercise. The lactic acid thus formed is broken down by the supply of oxygen.
Detailed explanation-2: -During anaerobic glycolysis, the reduced cofactor, NADH+ H+ (which equals NADH2), formed by the enzyme GAPDH is reconverted to NAD+ during the formation of lactate. The overall reaction produces two molecules of ATP, independently of oxygen. Thus, during anaerobic glycolysis, protons are not formed.
Detailed explanation-3: -1: Lactic acid fermentation: Lactic acid fermentation is common in muscle cells that have run out of oxygen. The enzyme used in this reaction is lactate dehydrogenase (LDH).
