- Acid phosphatases are an important group of enzymes that can be detected in human blood serum. Under slightly acidic conditions (pH 5.0), this group of enzymes can hydrolyze biological phosphate esters as follows: R-O-P-O;² + H 20 → R-OH + HO-P-O;² Acid phosphatases are produced and can be detected in erythrocytes, kidney, spleen, the liver, and prostrate gland. The enzyme from the prostrate gland is clinically important because an increased activity in the blood is frequently an indication of cancer of the prostrate gland. Tartrate ion can strongly inhibit the phosphatase from the prostrate gland, but not acid phosphatases from other tissues. How can you use the information above to develop a specificIn addition to O, binding, changes in other chemical conditions can result in hemoglobin changes. pH is one of those factors. It can be understood by reaction #1. Red blood cells have the enzyme Carbonic Anhydrase which catalyzes reaction #2. Using the two reactions explain how pH contributes to the transfer of O2 from the lungs to the tissues. H-Hb* + O2 Hb-O2 + H* Reaction #1 CO2(aq) + H2O= H* + HCO3 Reaction #2Carbonic anhydrase is an extremely efficient enzyme in red blood cells that performs the essential function of trapping C02 coming out of tissues and hydrating it with H,0. The product of this reaction is which dissociates into a proton and a (Hint: the reaction is H20 + CO2 +„H+ bicarbonate; carbonic acid carbonic acid; carbonate carbonate; carbonic acid carbonate; bicarbonate carbonic acid; bicarbonate
