Effect of Exercise on a Heart Rate The Science Oxygen + Glucose = Carbon Dioxide + Energy (ATP) When you exercise, you increase the need of energy for your body. This Energy, or Adenosine Tri-Phosphate (ATP), is produced from oxygen and glucose. To get more oxygen into our body, we breathe faster, bringing more oxygen in to our lungs, and our heart rate increases, pumping this oxygen to our cells faster. The oxygen breaks down the glucose in the cells then produces the energy needed to continue your exercise. This is called aerobic respiration, meaning it uses oxygen. If you need more energy, then the body uses a process called anaerobic respiration, which means not requiring oxygen. An enzyme in your cells breaks down the glucose into two molecules of pyruvic acid. This gives off your energy, but the pyruvic acid is broken down further into lactic acid (carbon dioxide and ethanol). Because lactic...
