What are the major transport mechanisms for $$CO_2$$ Explain?

##### Solution :-

● Through plasma:

Approximately 7% of the CO2 is transported through the plasma in a dissolved state. Carbon dioxide will combine with the water to form

As the process of forming carbonic acid is slow, only a small amount of carbon dioxide is carried this way.

● Through RBCs:

Approx 25% of CO2 is transported with the help of red blood cells as carbaminohemoglobin. Carbon dioxide will bind to the amino groups on the polypeptide chains of hemoglobin and form a compound which is known as carbaminohemoglobin.

● Through sodium bicarbonate:

Approximately 70% of CO2 is transported within the sort of sodium bicarbonate. As CO2 diffuses into the plasma, an outsized amount of it combines with water to make acid within the presence of the enzyme carbonic anhydrase. Carbonic anhydrase is an enzyme that contains zinc that accelerates the formation of acid. This carbonic acid formed will dissociate into bicarbonate $$(HCO_3^{ –})$$ and hydrogen ions (H+).
