Question

The energy yield in terms of $ATP$ is higher in aerobic respiration than anaerobic respiration. Why anaerobic respiration occurs even in organisms that live in aerobic condition like human beings and angiosperm.

Answer 1

Explanation

● When the oxygen concentration is low in some of the body parts such as skeletal muscles during strenuous exercise, then cells prefer to undergo anaerobic respiration to meet its energy requirements in human beings.

● Anaerobic respiration will provide less energy but in a shorter time.

● Thus in cases where there is a lack of oxygen but energy is required, anaerobic respiration occurs in aerobes like human and angiosperms.
