Question

What is anaerobic respiration? Does it occur in the human body also?

Answer 1

The breakdown of glucose to obtain energy in the absence of oxygen to give carbon dioxide and alcohol is termed as anaerobic respiration. Several organisms such as yeast and bacteria can live without oxygen as they carry out anaerobic respiration.
Yes, anaerobic respiration occurs in the human body also. During strenuous activities, body needs more energy but cannot get enough oxygen. Thus, anaerobic respiration occurs in the muscle cells to provide additional energy.
