Question
When does anaerobic respiration occur in man and yeast?
✓

Answer

Anaerobic respiration occurs in man in muscles at the time of excessive exercising. Blood supply does not meet the oxygen demand of the exercising body. At that time in muscle, lactic acid is produced as a result of anaerobic respiration. In yeast also, anaerobic respiration occurs in the condition of absence of oxygen.
