The two step reaction catalyzed by isocitrate dehydrogenase involves: A.β-decarboxylation expelling the α-keto carboxyl as CO2. B.oxidation of the C-2 alcohol of isocitrate to form oxalosuccinatE. C.oxidation of the C-2 alcohol to form oxaloacetatE. D.β-elimination expelling the central carboxyl group as CO2.
