When does anaerobic respiration occurs in our body? Give an example.

The anaerobic respiration occurs in our body when there is lack of oxygen during exercise.

human muscle cells undergo utilize anaerobic respiration when they lack sufficient oxygen or require a quick energy.

As a result of anaerobic respiration lactic acid is formed in the mucle cells which cause fatigue and muscle cramps after prolonged exercise.

The anaerobic respiration chemical reaction is given below:

Glucose →Pyruvate +Energy→ 2 latic acid + 2 ATP
