[{'content': 'In a seriously ill patient, addition of amino acids in the diet results in a positive nitrogen balance. The mechanism for this is \nSelect and explain. \nA. Increased absorption of amino acids from the intestine, B. Enhanced rates of gluconeogenesis, C. Increased secretion of insulin, D. Increased Growth hormone secretion', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Glucose, mannose, aminoacids (such as leucine, arginine, others) and\xa0β\xa0ketoacids such as acetoacetate (derived from fat catabolism) stimulate insulin secretin and have protein sparing effect.\nInsulin has anabolic effect on metabolism. It decreases protein catabolism and fat catabolism for energy production and increases aminoacid uptake and protein synthesis (positive nitrogen balance).', 'role': 'assistant'}]
