Question

Discuss "The respiratory pathway is an amphibolic pathway.

Answer 1

During synthesis of fatty acids, acetyl CoA is withdrawn from respiratory pathway. Also, in the synthesis of proteins, respiratory substrates get withdrawn. Thus, respiration is also involved in anabolism. Therefore,respiration can be termed asamphibolic pathway as it involves both anabolism and catabolism.

Answer 2

Answer:

Due to involvement of respiratory pathway in both the anabolism as well as catabolism of the body it is considered as amphibolic pathway.

Explanation:

Respiration is commonly thought to be a catabolic procedure as it involves breaking of substance and release of energy. For example, starches are separated to glucose before entering respiratory pathways. Fats get changed into fatty acid and glycerol and in turn fatty acid gets changed over into acetyl CoA before entering the respiratory pathway. The protein undergoes deamination process before participating in pathway.

During production of fatty acid, acetyl CoA is pulled back from respiratory pathway. Additionally, in the blend of proteins, respiratory substrates get pulled back. In this manner, respiration is additionally associated with anabolism.

Thus, respiratory pathway is termed as amphibolic pathway as it includes both anabolism and catabolism.
