Question

Given below shows a cycle discovered by Hans Krebs. It involves stepwise oxidative and cyclic degradation of activated acetate derived from pyruvate. Study the given figure and answer the following directions.\ In which of the following steps $\mathrm{NAD}^{+}$gets reduced to $\mathrm{NADH}^{+}$?\

Professor PC Thomas Classes · Answer

(c): There are three points in the citric acid cycle where $\mathrm{NAD}^{+}$is reduced to $\mathrm{NADH}+\mathrm{H}^{+}$: (i) Isocitrate to oxalosuccinate (ii) $\alpha$-ketoglutarate to succinyl COA (iii) Malate to oxaloacetate.
