Why is respiratory pathway referred

Respiratory pathway referred to as an amphibolic pathway because it comprises of the breakdown of substrates. The fatty acids are broken down into Acetyl CoA.

Similarly, glycerol also enters a biochemical pathway and gets broken down into PGAL (3-phosphoglyceraldehyde). The amphibolic pathway involves both anabolic and

catabolic pathway. Respiration can cause both the breakdown and synthesis of fatty acids. Thus it can be said to be an amphibolic pathway.
