पर्याय

• It reduces CO₂ transport

• It reduces O₂ transport

• It increases CO₂ transport

• It increases O₂ transport

Answer 1

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.
