Question:

In the human body, CO₂ is primarily carried in blood as

Options:

1. Dissolved in plasma
2. Carbaminohaemoglobin
3. Sodium bicarbonate
4. Potassium carbonate

Solution:

When carbon dioxide (CO₂) dissolves in water, it forms carbonic acid (H₂CO₃), which can quickly dissociate into bicarbonate ion (HCO₃⁻) and hydrogen ion (H⁺). This reaction is facilitated by the enzyme carbonic anhydrase. The bicarbonate ion is transported in the plasma, while the hydrogen ion combines with hemoglobin to buffer the blood and prevent acidosis. Most of the carbon dioxide in the blood is transported in the form of bicarbonate ion. This process is called the bicarbonate buffer system, and it is the primary way that the body regulates blood pH. Some carbon dioxide is also carried in the blood by binding to hemoglobin as carbaminohemoglobin, but this is a minor mechanism compared to the bicarbonate buffer system. Carbon dioxide is only minimally soluble in plasma and cannot be carried in the blood by itself.
