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: -Lactic acid is the waste product produced during anaerobic respiration. Running fast can lead to a build-up of lactic acid in your muscles, causing cramp.

Detailed explanation-3: -Anaerobic respiration in humans Anaerobic respiration releases less energy than aerobic respiration but it does this more quickly. The product of this reaction is lactic acid. This builds up in muscles causing pain and tiredness, which can lead to cramp.

Detailed explanation-4: -Aerobic respiration requires oxygen and glucose and produces carbon dioxide and water. Anaerobic respiration occurs in the absence of oxygen, as it only requires glucose. In animal cells and some bacterial cells, anaerobic respiration produces lactic acid.
