So carbonic anhydrates essentially hydrates. So it combines carbon dioxide with water to produce carbonic acid. And carbonic acid, being a relatively strong acid, will dissociate into these two polar ions, hydrogen ions and bicarbonate ions. Now, carbonic anhydrates is a very efficient, very effective enzyme, like most enzymes are. In fact, this molecule can convert. The enzyme can transform 1 million of these carbon dioxide molecules every single second.
