Introduction:

Glucose is the main source of energy for all the cells and excess of blood glucose is stored in the form of glycogen in the liver and skeletal muscles. This stored glucose is utilized when the blood glucose level lowers down. Insulin and glucagon hormones regulate the blood glucose level. Insulin stimulates a decrease in the glucose level to the normal range whereas glucagon increases the blood glucose concentration.
