It is a vital process that occurs inside the human body to aid in other biological reactions like energy production.
This metabolism involves both catabolism and anabolism reactions.
Catabolism splits larger organic molecules into smaller ones and energy is released during reaction whereas anabolism synthesizes complex molecules from simpler ones and it requires energy for formation.
These both work together in all organisms to produce energy and repair cells.
Amino acids act as intermediates for the Krebs cycle as pyruvate or acetyl CoA.
End Product: Amino acid metabolism end products are glutamate which results in pyruvate or Acetyl CoA.
