Insulin:A hormone produced by the pancreas that allows your body to use sugar (glucose) from carbohydrates in the food you eat for energy or to store glucose for future use.
Glucagon: Another hormone produced by the pancreas which works with insulin to maintain proper blood sugar levels. When blood sugar is low, glucagon signals the liver to release stored glucose.
