In a seriously ill patient, addition of amino acids in the diet results in a positive nitrogen balance. The mechanism for this is:: (A) Increased absorption of amino acids from the intestine, (B) Enhanced rates of gluconeogenesis, (C) Increased secretion of insulin, (D) Increased Growth hormone secretion
Answer is C. C i.e. Increased secretion of insulin- Glucose, mannose, aminoacids (such as leucine, arginine, others) and f3 ketoacids such as acetoacetate (derived fromfat catabolism) stimulate insulin secretin and have protein sparing effectQ.- Insulin has anabolic effect on metabolism. It decreases protein catabolism and fat catabolism for energy production and increases aminoacid uptake & protein synthesis (positive nitrogen balance)Q.
