Carbonic anhydrase converts carbon dioxide to bicarbonate primarily in red blood cells.

Step 2 the dissociation of carbonic acid into bicarbonate and a proton is a spontaneous phenomenon. They are therefore classified as metalloenzymes. This chemical reaction is essential for the life of prokaryotes and eukaryotes.

Seven genetic families of CAs have been discovered to date the α- β γ- δ- ζ- η- and θ-CAs which have been characterized by kinetic and X-ray crystallographic studies allowing a deep understanding of the structurefunction relationship. Which best describes the action of carbonic anhydrase. In summary the carbon dioxide produced by the cells is converted within the systemic capillaries mostly through the action of carbonic anhydrase in the red blood cells to carbonic acid.
