[{'content': 'Which of the following enzyme is NAD+ dependent? \nSelect and explain. \nA. HMG CoA reductase, B. Glycerol-3-phosphate dehydrogenase, C. Acyl CoA dehydrogenase, D. Succinate dehydrogenase', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Dehydrogenases:\xa0\nThese enzymes cannot utilize oxygen as hydrogen acceptor.\xa0\nThey catalyse the reversible transfer of hydrogen from one substrate to another and, thus, bring about oxidation reduction reactions.\xa0\nThere are a large number of enzymes belonging to this group\nNAD+ dependent dehydrogenases, e.g. alcohol dehydrogenase, glycerol 3-phosphate dehydrogenase.\nNADP+ dependent dehydrogenasese,.e.g. HMC CoA reductase ,enoyl reductase.\nFMN dependent dehydrogenasese,. e.g. NADH dehydrogenase.\nFAD dependent dehydrogenasese, e.g. succinate dehydrogenase, acyl CoA dehydrogenase.\nThe cytochromes: All the cytochromes of electron transport chain (b, c, and c) except the terminal cytochrome oxidase (a+a3) belong to this group.\nKey Concept:\nDehydrogenases catalyse the reversible transfer of hydrogen from one substrate to another and, thus, bring about oxidation reduction reactions.\nNAD+ dependent dehydrogenases, e.g. alcohol dehydrogenase, glycerol 3-phosphate dehydrogenase\nRef : Textbook of Biochemistry, Satyanarayana', 'role': 'assistant'}]
