Oxygen carrying capacity of blood is reduced by

A

`CO_(2)`

B

CO

C

`SO_(2)`

D

`O_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
CO is a poisonous gas which binds with Hb more rapidly than `O_(2)` to form carboxyhaemoglobin.
CO makes the most stable combination with the Hb of blood. CO has 200-250 times more affinity for Hb as compared to `O_(2)`.
When inhaled air contains CO gas then persoii suffers from suffocation because product cannot dissociate so decreases free oxygen.
