Question

Respiratory pathway is an amphibolic pathway. In respiration, there is breakdown of many substances (catabolism) and synthesis of many substances (anabolism) by respiratory intermediates.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

If both assertion and reason are true and reason is the correct explanation of assertion

Answer 2

The term amphibolic is given to a biochemical pathway that involves both catabolism, i.e., breakdown of some substances and anabolism i.e., synthesis of some substances. In cellular respiration, both anabolism and catabolism occur during oxidation of respiratory substrate to release energy.
