Verified By Collegedunia
The Correct Option is D
Solution and Explanation
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 $CO_2$ is produced.
Pyruvic $+ CoA + NAD^+ {->[Mg^{2+}][\text{Pyruvate dehydrogenase}]}$
Acetyl $CoA + CO_2 + NADH+ H^+$
Acetyl CoA enters the TCA cycle.
