Detailed explanation-1: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-2: -Managing breakdown of protein and lipids due to changes in fat cells. Uptake of amino acids and potassium into the cells that cannot take place in the absence of insulin. Managing the excretion of sodium and fluid volume in the urine. Enhancing the memory and learning capabilities of the brain.

Detailed explanation-3: -Insulin is a hormone created by your pancreas that controls the amount of glucose in your bloodstream at any given moment. It also helps store glucose in your liver, fat, and muscles. Finally, it regulates your body’s metabolism of carbohydrates, fats, and proteins.

Detailed explanation-4: -Insulin Function When the body digests food rich in carbohydrates, glucose is released into the bloodstream. This leads to an increase in blood glucose levels in the body. Consequently, the pancreas sends chemical signals in the form of insulin that direct all the cells in the body to take in the glucose.

Detailed explanation-5: -The function of insulin hormone is to lower the blood sugar level. Insulin controls the metabolism of sugar. Deficiency of insulin causes diabetes. Diabetic patients are treated by giving injections of insulin.
