Oxidative decarboxylation of pyruvic acid results in the formation of I. Acetyl CoA II. CO2 III. ATP IV. NADH + H+

Question

Oxidative decarboxylation of pyruvic acid results in the formation of I. Acetyl CoA II. CO2 III. ATP IV. NADH + H+ (A) I only (B) I and II only (C) I, II and III only (D) I,II and IV only

Tardigrade Admin · Accepted Answer

Pyruvate formed during glycolysis enters mitochondrial matrix and undergoes oxidative decarboxylation by a complex set of reactions catalysed by pyruvic dehydrogenase and NADH, acetyl CoA and

C O_{2}

is produced.
Pyruvic

+ C o A + N A D^{+} M g^{2 +} Pyruvate dehydrogenase

Acetyl

C o A + C O_{2} + N A DH + H^{+}

Acetyl CoA enters the TCA cycle.
