23 c. An enol is the nucleophile while an enolate is the electrophile.d. A carbonyl group (aldehyde or ketone) is the electrophile while an enolate is the nucleophile.23. The organic chemist decarboxylates beta-ketoacids at acidic pH values. In the mitochondria the pH isaround 7. What does this mean in terms of the mechanism of beta-ketoacid acid decarboxylation ofisocitrate in the enzyme active site?a. The carboxylate may still decarboxylate in the environment of the enzyme active site.b. The carboxylate maybe converted to the acid form in the environment of the enzyme active site priorto decarboxylation.c. The carboxylate may still decarboxylate in the environment of the enzyme active site due to thepresence of NAD+.d. Both a & b maybe correct.24. In the Krebs cycle isocitrate is oxidized to oxalosuccinic acid (also called alpha-ketoglutarate). Whatelse happens in this step?a. NADH is oxidized to NAD+.b. NAD+ is reduced to NADH.c. Isocitrate decarboxylates.d. both b & c

The carboxylate may still decarboxylate in the environment of the enzyme active site. - The carboxylate maybe converted to the acid form in the environment of the enzyme active site pri o decarboxylation. The carboxylate may still decarboxylate in the environment of the enzyme active site due to the resence of NAD+.
