WebCO 2 diffuses down its concentration gradient out of tissues and into red blood cells (RBCs). Once inside the RBC, the enzyme carbonic anhydrase catalyses the conversion of CO 2 into carbonic acid (H 2 CO 3). Carbonic acid is then hydrolysed into H + ions and HCO 3 – (bicarbonate). The H + ion is bound by haemoglobin which buffers the process WebDec 20, 2024 · A faster reaction at higher pH, when more OH- ions are present, suggests OH- is involved in the rate determining step. However, realistically, the pH of human blood cannot be changed to speed up hydration of CO2. Instead, humans use carbonic anhydrase to catalyse the reaction. When CA is present, the reaction is sped up to a rate of k = 106 s-1.

WebCarbonic anhydrase produces carbon dioxide in all cells by metabolism. The red blood cells remove it from the body. With the help of Carbonic anhydrase, the red blood cells convert a majority of CO 2 to bicarbonate for transport. After that, the CO 2 is exhaled out from the lungs. Carbonic anhydrase can also act as an inhibitor for therapeutic ... WebCarbonic anhydrase is a metalloenzyme that accelerates the interconversion between CO2 and H 2 O, and H 2 CO 3 (carbonic acid) and its dissociative ions (HCO 3− and H + ). Carbonic anhydrase regulates pH and assists in the transport of CO 2.
