Vedclass · Answer

(A) Proteins are complex macromolecules that cannot be directly utilized in the respiratory pathway. They are first broken down by proteases into their constituent monomers,which are amino acids. These amino acids are then deaminated and enter the respiratory pathway at various stages,such as pyruvate,acetyl-CoA,or intermediates of the Krebs cycle,to be oxidized for energy production.

Protein cannot be used directly as a respiratory substrate; it breaks down into which of the following?
