What Does Anaerobic Respiration Mean?
Anaerobic respiration is a form of respiration that is contrasted with aerobic respiration in that it does not use oxygen. It is an alternative method of respiration that is used when oxygen is not present and derives energy from other chemicals nearby or within the body. Aerobic respiration produces more energy and is 15 times more efficient than anaerobic respiration. This is why most large creatures breathe to take in oxygen.
