<P> The bicarbonate buffer system is an acid - base homeostatic mechanism involving the balance of carbonic acid ( H CO ) , bicarbonate ion ( HCO − 3 ) , and carbon dioxide ( CO ) in order to maintain pH in the blood and duodenum , among other tissues , to support proper metabolic function . Catalyzed by carbonic anhydrase , carbon dioxide ( CO ) reacts with water ( H O ) to form carbonic acid ( H CO ) , which in turn rapidly dissociates to form a bicarbonate ion ( HCO − 3 ) and a hydrogen ion ( H ) as shown in the following reaction : </P>
