These insulins work for between eight and 40 hours, depending on the type. If blood sugar levels are low, glucagon tells your body to break down glycogen (stored glucose) in the liver to release glucose and increase glucose levels. Whereas, if the blood glucose level is too low, the liver receives a message to release some of that stored glucose into the blood. Insulin controls whether sugar is used as energy or stored as glycogen. Insulin helps your cells take up glucose and use it as energy - or store it for future use. Insulin and glucagon are instrumental in the regulation of blood glucose levels, allowing cells to receive proper nutrients.
