[{'content': 'What are the enzymes required for the formation of Phosphoenolpyruvate from Pyruvate? \nSelect and explain. \nA. Pyruvate dehydrogenase and Pyruvate carboxylase, B. Lactate Dehydrogenase and Pyruvate Dehydrogenase, C. Pyruvate carboxylase and Phosphoenolpyruvate Carboxykinase, D. Phosphoenolpyruvate carboxykinase and Pyruvate Dehydrogenase', 'role': 'user'}, {'content': "Answer: C \nExplanation: Ans. is 'c' i.e., Pyruvate carboxylase and Phosphoenolpyruvate CarboxykinasePyruvate conversion to Phosphoenol pyruvate is a pa of gluconeogenesis, Pyruvate is conveed to Oxaloacetate by Pyruvate Carboxylase, Pyruvate Carboxylase requires Biotin as coenzyme. It uses Carbondioxide in the form of Bicarbonate. It uses ATP as a source of energy.", 'role': 'assistant'}]
