Carbon monoxide, when in haled , combines with blood haemoglobin to form carboxy-haemoglobin at a rate 210 times faster than the rate at which oxygen forms oxyhaemoglobin. Thus, respiration is impaired.

How does carbon monoxide prevent transport of oxygen into the body tissues?
Explanation:
Carbon monoxide (CO) is a poisonous gas emitted by automobiles and other sources. It is particularly dangerous because it interferes with the transport of oxygen in the body, leading to severe health consequences.
Formation of a stable compound with haemoglobin:
The correct answer is option 'B' - carbon monoxide prevents the transport of oxygen by forming a stable compound with haemoglobin. Haemoglobin is the protein responsible for carrying oxygen in the blood. When carbon monoxide is inhaled, it binds to the haemoglobin molecule, forming a compound called carboxyhaemoglobin.
Effect on oxygen transport:
The formation of carboxyhaemoglobin reduces the capacity of haemoglobin to bind with oxygen. This means that even if there is enough oxygen in the environment, the body tissues are unable to receive an adequate supply. As a result, the affected individual may experience symptoms of oxygen deprivation, such as dizziness, shortness of breath, confusion, and in severe cases, organ damage or death.
Strong binding affinity:
Carbon monoxide has a much higher affinity for haemoglobin than oxygen. This means that it readily displaces oxygen from the binding sites on the haemoglobin molecule and forms a more stable bond. The bond between carbon monoxide and haemoglobin is also difficult to break, leading to a prolonged effect on oxygen transport.
Preventing oxygen release:
Furthermore, the binding of carbon monoxide to haemoglobin alters its structure, making it less likely to release oxygen to the tissues. This further contributes to the reduced oxygen-carrying capacity of the blood.
In conclusion, carbon monoxide prevents the transport of oxygen into the body tissues by forming a stable compound with haemoglobin. This prevents the binding of oxygen to haemoglobin and reduces the oxygen-carrying capacity of the blood, leading to oxygen deprivation in the tissues. It is crucial to minimize exposure to carbon monoxide to prevent its detrimental effects on human health.
