Which of the following are not used in the conversion by pyruvate to acetyl CoA? (i) Oxidative dehydrogenation (ii) Oxidative dehydration (iii) Oxidative phosphorylation (iv) Oxidative decarboxylation
1 (i), (ii) and (iii)
2 (i) and (ii)
3 (ii) and (iv)
4 (i) and (iii)
Explanation:
The conversion of pyruvate to acetyl CoA involves oxidative decarboxylation (removal of a carboxyl group) and removal of hydrogen which is taken up by \(\mathrm{NAD}^{+}\)to become \(\mathrm{NADH}^{+}\)
