In TCA cycle, NADH is produce at all sites except -: (A) Isocitrate dehydrogenase, (B) Succinate dehydrogenase, (C) Malate dehydrogenase, (D) a Ketoglutarate dehydrogenase
Answer is B. Ans. is 'b' i.e., Succinate dehydrogenase NADH is produced and CO , is liberated at 3 steps :Conversion of isocitrate to a-ketoglutarate by isocitrate dehydrogenaseConversion of a-ketoglutarate to succinyl CoA by a-ketoglutarate dehydrogenaseConversion of L-malate to oxaloacetate by malate dehydrogenase.
