Question
It is known that exposure to carbon monoxide is harmful to animals because ______.
Options
It reduces CO2 transport
It reduces O2 transport
It increases CO2 transport
It increases O2 transport
Solution
It is known that exposure to carbon monoxide is harmful to animals because It reduces O2 transport.
Explanation:
CO is a poisonous gas which binds with Hb more rapidly than O2 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 O2. When the inhaled air contains CO gas then a person suffers from suffocation because the product cannot dissociate so decreases free oxygen.
