<prompt> In a seriously ill patient, addition of amino acids in the diet results in a positive nitrogen balance. The mechanism for this isIncreased absorption of amino acids from the intestineEnhanced rates of gluconeogenesisIncreased secretion of insulinIncreased Growth hormone secretion  <response>: Glucose, mannose, aminoacids such as leucine, arginine, others and β ketoacids such as acetoacetate derived from fat catabolism stimulate insulin secretin and have protein sparing effect.Insulin 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.
