How are glutamic acid,glutamine,proline,and arginine related to the process of amino acid biosynthesis?

Question

Quizplus · Accepted Answer

Glutamic acid, glutamine, proline, and arginine are all derived from alpha-ketoglutarate in the process of amino acid biosynthesis. Alpha-ketoglutarate is a key intermediate in the Krebs cycle, which is involved in energy metabolism and serves as a precursor for many different metabolic pathways, including amino acid biosynthesis.
