Insulin helps your cells take up glucose and use it as energy - or store it for future use. You get glucose from carbohydrates in the food you eat. It is a large multi-branched polymer of glucose which is accumulated in response to insulin and broken down into glucose in response to glucagon. Glucagon helps blood glucose levels rise back up in multiple ways, including: If your blood glucose levels trend higher, your pancreas releases insulin to bring it back into range. Glycogen is a stored form of glucose (sugar). 1) Enhances release of glucose from glycogen; 2) Enhances release of fatty acids from adipose tissue.
