SECTION A

1a. Using a metabolic pathway only, describe the biosynthesis of Serine amino acid.
Serine is synthesized from 3-phosphoglycerate, an intermediate of glycolysis.

3-Phosphoglycerate dehydrogenase* oxidizes 3-phosphoglycerate to 3-phosphohydroxypyruvate.
This reaction uses $\text{NAD}^+$ as a cofactor.
Phosphoserine aminotransferase* transfers an amino group from glutamate to 3-phosphohydroxypyruvate, forming phosphoserine and $\alpha$ -ketoglutarate.
Phosphoserine phosphatase* hydrolyzes phosphoserine to
