[{'content': 'In starvation activities of all of the following enzyme is increased except ? \nSelect and explain. \nA. Pyruvate carboxylase, B. Pyruvate kinase, C. PEP carboxykinase, D. Glucose 6 phosphatase', 'role': 'user'}, {'content': 'Answer: B \nExplanation: In starvation activity of all enzymes responsible for gluconeogenesis are increased.\nPyruvate kinase is the enzyme of glycolysis. Activity of enzymes of glycolysis are suppressed in starvation. So pyruvate kinase activity is suppressed in starvation.\nAll other enzymes given in this question are gluconeogenic\nenzyme whose activity is enhanced in starvation.', 'role': 'assistant'}]
