Assertion `CO_(2)` transport occurs very fast through RBCs.
Reason : Enzyme carbonic anhydrase is absent in blood plsama.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion

B

Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion

C

Assertion is true, but Reason is true

D

Assertion is false and Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Transport of `CO_(2)` by blood is much easier than that of oxygen due to high solubility of `CO_(2)` in water. About 70% of `CO_(2)` is transported through RBCs. `CO_(2)` entres in RBCs , where it reacts with water to from carbonic acid in the presence of carbonic anhydrase. most of the carbonic acid rapidly dissociates to form bicarbonate and hydrogen ions.
