In fat tissue, insulin increases glucose uptake and the use of glucose to form lipids and suppresses lipolysis. Insulin also stimulates the uptake of amino acids and formation of protein in skeletal muscle and suppresses protein breakdown in the liver. Secretion of insulin rises in response to increased blood glucose concentration. When glucose concentration falls to normal insulin secretion drops back to basal levels.
A summary of the actions of insulin on glucose, protein and lipid metabolism.
