A molecule that blocks the activity of carbonic anhydrase would cause an increase in blood pH.
Zinc-containing enzymes called carbonic anhydrases catalyze the reversible conversion of CO2 and bicarbonates (carbon dioxide hydration and bicarbonate dehydration). Its entry into the cell is facilitated by the conversion of bicarbonate to CO2. However, the process that turns CO2 into bicarbonate aids in keeping the gas inside the cell.
All living things require this enzyme to maintain the proper acid-base balance (regulates pH). For instance, carbonic anhydrases cause the stomach to produce acid, which decreases pH levels.
