Exercise lowers modest amounts of blood glucose and boosts the body's sensitivity to insulin.
Blood glucose is the concentration of sugar dissolved in the blood of a person. It is the prime source of energy for the body. When the blood glucose is very high, the person is likely to be diabetic. Exercise is necessary to burn the excessive glucose molecules in order to gain energy for the exercise.
Insulin is a polypeptide which regulates the glucose levels in the body. It is secreted by the pancreatic cells called Islets of Langerhans. The structure is composed of two chains: A chain and B chain, joined together by the disulfide bonds.
