Question
During exercise, most carbon dioxide is transported principally as bound to hemoglobin. as dissolved CO 2 in solution in the blood. bicarbonate. bound to myoglobin.
Solution
During exercise, most carbon dioxide is transported principally as bicarbonate. Here's a step-by-step explanation:
- When you exercise, your muscles produce carbon dioxide as a waste product.
- This carbon dioxide diffuses out of your muscle cells and into your blood.
- In the blood, carbon dioxide can be transported in three ways: dissolved in solution, bound to hemoglobin, or converted into bicarbonate.
- 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.
- The bicarbonate ions are then transported in your blood to your lungs.
- In your lungs, the process is reversed: bicarbonate and hydrogen ions combine to form carbonic acid, which then splits into water and carbon dioxide.
- The carbon dioxide is then exhaled, completing the process of carbon dioxide transport and removal.
