Answer:
The largest source of carbons for gluconeogenesis is pyruvate ( synthesized from acetyl-CoA )
Explanation:
As the process of gluconeogenesis is the reverse of glycolysis , it begins with pyruvate ( being the source of carbons for gluconeogenesis ) .
The lactate is oxidized to pyruvate by lactate dehydrogenase.
The amino acid alanine is converted to pyruvate by alanine aminotransferase.
Glycerol 3 phosphate is oxidized to dihydroxyacetone phosphate by glycerol 3 phosphate dehydrogenase.
As the pyruvate is formed , it is acted upon by pyruvate carboxylase enzyme and converted into OAA thus acting as the source of carbons.
The detail of the gluconeogenesis is given in the attached picture.
