During exercise, most carbon dioxide is transported principally as bicarbonate. Here's a step-by-step explanation:

1. When you exercise, your muscles produce carbon dioxide as a waste product.
2. This carbon dioxide diffuses out of your muscle cells and into your blood.
3. In the blood, carbon dioxide can be transported in three ways: dissolved in solution, bound to hemoglobin, or converted into bicarbonate.
4. The majority of carbon dioxide (about 70%) is transported as bicarbonate. This happens when carbon dioxide reacts with water in your blood to form carbonic acid, which quickly dissociates into bicarbonate and hydrogen ions.
5. The bicarbonate ions are then transported in your blood to your lungs.
6. In your lungs, the process is reversed: bicarbonate and hydrogen ions combine to form carbonic acid, which then splits into water and carbon dioxide.
7. The carbon dioxide is then exhaled, completing the process of carbon dioxide transport and removal.
