In a seriously ill patient, addition of amino acids in the diet results in a positive nitrogen balance. The mechanism for this is

Increased absorption of amino acids from the intestine

Enhanced rates of gluconeogenesis

Increased secretion of insulin

Increased Growth hormone secretion

Question Category:

Correct Answer:

Increased secretion of insulin

Description:

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).
