The enzyme that increases the reaction rate between `CO_(2)` and `H_(2)O` in red blood cell is

A

carbonic anhydrase

B

adenylate cyclase

C

carbonic synthetase

D

alkaline phosphatase.

Text Solution

Verified by Experts

The correct Answer is:
A

About `70%` of `CO_(2)` os transported in plasma in the form bof bicarbonates, `CO_(2)` diffuses into RBCs, combines with water and form carbonic acid. Carbonic acid being unstable quickly dissociates into bicarbonate ions and hydrogen ions. This reaction is thousand times faster in RBCs as compared to plasma, as RBCs contain carbonic anhydrase enzyme that reversibe catalyses the conversion of `CO_(2)` and water to carbonic acid.
