Why is respiratory pathway referred to as an amphibolic pathway?
Glucose is the favourite sulphate for respiration as carbohydrates are first converted into glucose. Prior to used for respiration. Fats are acetyl CO-A are broken down into glycerol and fatly acid which is further degraded into acetyl Co-A, while protein is degraded into, smaller units anino acids.
Respiratory process involves the breaking down of substrate is catabolic proceses. Sometime the fatty acid is required them synthesis of it occurs by withdrawing acetly Co-A. This synthesising phase is the anabolic process.
Thus, respiratory pathway involves the catabolic process (break down) and anabolic pathway synthesis of molecules using respiratory intermediates front link, it is called as an amphibolic pathway.
