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. Policy. Without the messenger insulin, cells cannot use glucose as fuel, which can lead to them not working properly. Glucagon has an opposite (antagonistic) effect to insulin. 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. After giving glucagon, someone should monitor the person for adverse effects. . Too little insulin is a problem usually seen in people with diabetes.
