[{'content': 'All are used in gluconeogenesis except ? \nSelect and explain. \nA. Oleate, B. Succinate, C. Glutamate, D. Aspaate', 'role': 'user'}, {'content': "Answer: A \nExplanation: Ans. is 'a' i.e., OleateSubstrate of gluconeogenesis are :Lactate (lactic acid)PyruvateAll amino acids (except leucine and lysine)PropionateIntermediates of citric acid cycleFatty acids are not substrates for gluconeogenesis.Coming to the questionFatty acids (oleate in the question) is not a substrate for gluconeogenesis.Succinate is an intermediate of TCA cycle, and is a substrate for gluconeogenesis.All amino acids (in the question glutamate and aspaate), except leucine and lysine are substrates for gluconeogenesis.", 'role': 'assistant'}]
