[{'content': 'Pyruvate can be conveed directly into all the following except : \nSelect and explain. \nA. Phosphoenol pyruvate, B. Alanine, C. Acetyl CoA, D. Lactate', 'role': 'user'}, {'content': 'Answer: A \nExplanation: A i.e. Phosphoenol PyruvatePyruvate can be directly conveed to acetyl CoA (by oxidative decarboxylation), oxaloacetate (by carboxylation), alanine (transamination); and lactate (in anaerobic conditions). But pyruvate can not be directly conveed to phosphoenol pyruvate (a reaction of gluconeogenesis)Q. However, phosphoenol pyruvate can be directly conveed to pyruvate (in glycolysis)Q.', 'role': 'assistant'}]
