Glucose is the Primary Source of Energy for Cells. Glucose is the human body's key source of energy as it provides energy to all the cells in our body. Glucose also is critical in the production of proteins, lipid metabolism and is a precursor for vitamin C production.
Homeostasis of Blood Glucose Levels. Glucose is the main source of fuel for the cells in our bodies, but it's too big to simply diffuse into the cells by itself. Instead, it needs to be transported into the cells. Insulin is a hormone produced by the pancreas that facilitates glucose transport into cells. By facilitating glucose transport into cells from the bloodstream, insulin lowers blood glucose levels. It also inhibits glucose production from amino acids, fatty acids and glycogen which, you may remember, is a carbohydrate composed of many glucose subunits.
