InterviewSolution

1.	Oxygen carrying capacity of blood is reduced byA. `CO_(2)`B. COC. `SO_(2)`D. `O_(3)`
Answer» Correct Answer - 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.
