D1 Blood glucose The glucose in your blood (also known as blood sugar, and another form of carbohydrate in your body) can sometimes be used as an energy source to make ATP, but it’s not the most ideal choice. During exercise your body prefers to maintain your blood glucose levels by several different actions rather than use it for energy.
