While there is plenty of glucose within the system, the body's cells cannot accept it, and suffer what's called intracellular hypoglycemia. In diabetes, insulin is not produced in adequate quantities, or some of the insulin is not accepted by the receptors. This allows the cells to accept and use glucose for fuel. Insulin receptors are cell sites which accept insulin. Insulin allows glucose to enter body cells, thus the body is able to use the glucose for its fuel. Glucose can't be used as fuel until it is able to enter the body's cells. Insulin uses receptors to enter body cells. It complements or counter-acts the breaking-down the catabolic (breaking-down) body processes of gluconeogenesis, lipolysis, (fat breakdown) and glycogenolysis (glycogen breakdown). In the cells themselves, insulin aids in the anabolic (a positive, building or maintaining process) processes of turning glycogen stored in the liver and in muscles, into energy, and helps transform fatty acids and protein into forms both useful and necessary to the body. With the insulin system working, insulin allows cells to use glucose found in the bloodstream, keeping them fed and preventing hyperglycemia. Without the insulin system, the body would burn fuel whenever it was available, instead of when it was most needed.Īctions of insulin-the anabolic (positive or energy-producing) bodily process are shown in green-the catabolic (negative or energy-using) ones are in red. It controls the rate at which the body's cells can take in fuel (glucose). Insulin is necessary to enable the body to perform normally.
