how does CO2 diffuse in the form of bicarbonate in RBC.
Explain!

The carbon dioxide (CO₂) is converted to carbonic acid (H₂CO₃) inside the red blood cells by an enzyme known as carbonic anhydrase. Carbonic acid produced is an unstable molecule which gets dissociated immediately into bicarbonate ions and hydrogen ions. Hence, Carbon dioxide is diffused as bicarbonate in the RBCs.
