Vedclass · Answer

(A) The reaction shown is the oxidative decarboxylation of pyruvic acid,which acts as a link reaction between glycolysis and the Krebs cycle.This reaction is catalyzed by the Pyruvate Dehydrogenase Complex.The Pyruvate Dehydrogenase Complex requires several cofactors,including $Mg^{2+}$ ions,$NAD^+$,$CoA$,$TPP$ (Thiamine pyrophosphate),and Lipoic acid.Among the given options,Pyruvate dehydrogenase with $Mg^{2+}$ is the correct combination.

Identify the enzyme and cofactor required for the following reaction:
Pyruvic acid + $CoA + NAD^+ \rightarrow$ Acetyl $CoA + CO_2 + NADH + H^+$
