Glucagon is a hormone produced by the pancreas that plays a vital role in regulating blood glucose levels. When blood sugar levels drop, glucagon signals the liver to convert stored glycogen into glucose and release it into the bloodstream. This mechanism helps to maintain homeostasis in energy levels, particularly during fasting or between meals. Additionally, glucagon promotes the utilization of fat for energy, which helps to ensure that the body has a continuous energy source during periods of low carbohydrate availability. Thus, glucagon is essential for overall metabolic health.
