When Does Anaerobic Respiration Occur In The Human Body ?
Anaerobic respiration occurs when oxygen is not available in sufficient amount. For example: During exercise, our muscles work very hard and require high amount of energy. Since the amount of oxygen is limited, our muscles shift to anaerobic respiration to generate more energy.
Anaerobic respiration occurs in your body when there is not enough oxygen to completely break down glucose for your energy needs. When you exercise vigorously, you force your muscles to work harder, until they eventually reach a point where your lungs can no longer supply sufficient oxygen.
