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

Step-by-step solution

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.
