Answer 1

Carbonic anhydrase

About 70% of CO

​

 is transported in plasma in the form of bicarbonates. CO

​

 diffuses into RBCs, combines with water and forms 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 reversibly catalyses the conversion of CO

​

 and water to carbonic acid. So, the correct answer is 'Carbonic anhydrase'.

Answer 2

Answer:

A) Carbonic anhydrase.

Explanation:

Carbonic anhydrase, which is found within red blood cells, catalyzes a reaction converting CO2 and water into carbonic acid, which dissociates into protons, and bicarbonate ions. Said to be “near perfection”, carbonic anhydrase is able to catalyze at a rate of 106 reactions per second.
