Blood transports the most carbon dioxide by which of the following?

Question

Quizplus · Accepted Answer

Carbon dioxide is transported in the blood primarily as bicarbonate ions. This process involves the conversion of CO2 into HCO3- by the enzyme carbonic anhydrase, which is found in red blood cells. The HCO3- ion then diffuses out of the red blood cells and into the plasma, where it is transported to the lungs for elimination. CO2 can also be bound to hemoglobin or dissolved in the plasma, but these modes of transport are much less efficient than bicarbonate ion transport. CO2 is not transported by myoglobin as myoglobin is responsible for the storage and transport of oxygen in muscle cells.
