4. 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 angiosperms?

Solution:

Anaerobic respiration happens in creatures that are normally aerobic, such as humans, when a muscle is overworked or stressed. Germination of seeds in angiosperms results in anaerobic respiration, which releases energy for the seedling to emerge from the soil.
