WebInsulin lowers blood glucose levels by enhancing the rate of glucose uptake and utilization by target cells, which use glucose for ATP production. It also stimulates the liver to convert glucose to glycogen, which is then stored by cells for later use. Insulin also increases glucose transport into certain cells, such as muscle cells and the liver. WebGlucagon and glycogen are not the same. Glycogen is a stored form of glucose (sugar). Your body primarily stores glycogen in your liver and muscles. Glucagon is a hormone …
