The carbonic anhydrases (or carbonate dehydratases) form a family of enzymes that catalyze the rapid interconversion of carbon dioxide and water to bicarbonate and protons (or vice versa), a reversible reaction that occurs relatively slowly in the absence of a catalyst.
carbon dioxide is a guardian of the ph of the blood which is essential for survival the buffer system in which carbon dioxide plays an important role is called the carbonate buffer it is made up of bicarbonate ions and dissolved carbon dioxide with carbonic acidthe carbonic acid can neutralize hydroxide ions which would increase the ph of the blood when added the bicarbonate ion can neutralize hydrogen ions which would cause a decrease in the ph of the blood when addedt is made up of bicarbonate ions and dissolved carbon dioxide with carbonic acid the carbonic acid can neutralize hydroxide ions which would increase the ph of the blood when added the bicarbonate ion can neutralize hydrogen ions which would cause a decrease in the ph of the blood when added
