Answer #1

Biotin

Biotin is a cofactor which is used to transfer carboxyl group by pyruvate carboxylase enzyme.

Pyruvate carboxylase is an enzyme which converts pyruvic acid to oxaloacetic acid.

Thiamine pyrophosphate is used by pyruvate dehydrogenase to transfer carboxyl group.

Pyruvate dehydrogenase is the enzyme which converts pyruvic acid to acetyl coenzyme a.

    Thiamine prophosphate (TPP) is a cofactor for several enzyme-catalyzed reactions that involve decarboxylation of alpha-Keto acids. The relevant portion of TPP is its thiazolium ring. TPP forms relatively stable carbanion and consequently is a strong nucleophole. Diagram a plausible mechanism whereby enzyme-associated TPP catalyze the decarboxylation of pyruvate:
