प्रश्न
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?

उत्तर
Anaerobic respiration even in organisms that live in aerobic conditions like human beings and angiosperms due to oxygen deficiency. In our skeletal muscles during strenuous exercise oxygen deficiency leads to anaerobic respiration. In germinating seeds anaerobic respiration leads to the release of energy for emerging the seedling from the soil.
