How is the bulk of carbon dioxide carried in blood?

Question

Quizplus · Accepted Answer

The bulk of carbon dioxide is carried in the blood as the bicarbonate ion in the plasma after first entering the red blood cells. This process is facilitated by the enzyme carbonic anhydrase, which converts CO2 and water into carbonic acid, which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ion is then transported out of the red blood cells and into the plasma to be carried to the lungs for elimination.
