During exercise, body requires more energy, to meet energy requirement, it uses up blood sugar at a faster rate. As a result blood sugar falls. In this situation cells in the pancreas secrete hormone glucagon. Glucagon directs the liver to convert stored glycogen to sugar. This makes sugar more available in the bloodstream which causes the blood sugar to rise. Hormone Insulin and glucagon work in sync. Glucagon instructs with the liver to raise blood sugar, while insulin lowers blood sugar.
