Wired Faculty App

What is the role of carbonic anhydrase in the transport of gases during respiration ?

Solution

Carbonic anhydrase is most efficient enzyme. 70% of CO₂ produced in R.B.C. combines with water in the presence of carbonic anhydrase to form carbonic acid (H₂CO₃₎ which splits to form H⁺ and HCO₃'. CO₂ as HCO₃' dissociates in the presence of carbonic anhydrase to form H₂O and CO₂. CO₂ passes from blood into air and is passed out along with expired air.
The carbonic anhydrase carries out the following reaction:
