An amphibolic pathway is

Discuss: 'The respiratory pathway is an amphibolic pathway'.

In metabolic pathways

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.

Which of the two statements together support that respiratory pathway is an amphibolic pathway , (i) Fats breakdown to glycerol and fatty acids, subsequently yields acetyl CoA (ii) In respiration C-C bonds of complex compounds breakdown through oxidation leading to release of energy (iii) Acetyl CoA from respiratory pathway is withdrawn for synthesis of fatty acids (iv) Proteins are degraded by protease to amino acids and enter the respiratory pathway

Respiratory pathway is believed to be a catabolic pathway. However nature of TCA cycle is amphibolic. Explain.
