Document Summary
Helps transport glucose from the blood into cells. Our bodies regulate blood glucose levels within a fairly narrow range to provide adequate. Stimulates the liver and muscles to take up glucose and convert it to glycogen glucose to the brain and other cells. Two hormones that play key role in regulating blood glucose: High blood glucose: insulin secretion, when blood glucose levels increase after a meal, the pancreas secretes insulin from the beta cells into the bloodstream, cellular uptake: Insulin stimulates glucose transporters within cells to travel to the cell membrane: the glucose is used in the cell to be used as energy, glucose storage: Insulin stimulates the storage of glucose in the body tissues: glucose stored as glycogen in the liver and muscles. Stimulates the breakdown of glycogen to glucose to make glucose available to cells of the body. Stimulates gluconeogenesis: the production of (cid:862)new(cid:863) glucose from amino acids.
