[{'content': 'Insulin promotes lipogenesis by all except \nSelect and explain. \nA. Decreasing cAMP, B. Increase glucose uptake, C. Inhibiting pyruvate dehydrogenase, D. Increasing acetyl CoA', 'role': 'user'}, {'content': 'Answer: C \nExplanation: BE CAREFUL: Questions says EXCEPT Insulin: Decreases cAMP Increases glucose uptake into peripheral tissues by recruiting GLUT-4 Increase the formation of Acetyl CoA by increasing the action of enzyme - Pyruvate Dehydrogenase i.e. Link reaction So, option C is wrong as insulin activates enzyme of Link reaction i.e. Pyruvate Dehydrogenase (not inhibits). Extra information: Insulin activates: All Anabolic pathways (HMP, Glycogenesis, Fatty Acid Synthesis, Cholesterol Synthesis and TG Synthesis). Two Catabolic pathway enzymes i.e. Glycolysis and Link reaction.', 'role': 'assistant'}]
