Question

Oxidative decarboxylation of pyruvic acid results in the formation of
I. Acetyl CoA
II. $C{O}_2$
III. ATPIV. NADH + $H^{+}$

• A. I only
• B. I and II only
• C. I, II and III only
• D. I, II and IV only
• E. III and IV only

Answer 1

The correct option is D I, II and IV only

Oxidative decarboxylation of pyruvic acid occurs in the link reaction. In that, pyruvic acid is oxidised by removal of H2 and decarboxylated by removal of CO2 to produce acetyl CoA. The H2 that is released reduces NAD to NADH2.

So the answer is 'I, II and IV only'.
