GENERAL KNOWLEDGE

Detailed explanation-1: -Carbon monoxide has 210 times greater affinity for haemoglobin than oxygen1. A small environmental concentration will thus cause toxic levels of carboxyhaemoglobin .

Detailed explanation-2: -Carbon monoxide which is a poisonous compound combines readily with haemoglobin leaving no space for oxygen to combine and results in the toxication of the body.

Detailed explanation-3: -Hemoglobin binds carbon monoxide (CO) 200 to 300 times more than with oxygen, resulting in the formation of carboxyhemoglobin and preventing the binding of oxygen to hemoglobin due to the competition of the same binding sites.

Detailed explanation-4: -Carbon monoxide poisoning occurs when carbon monoxide builds up in your bloodstream. When too much carbon monoxide is in the air, your body replaces the oxygen in your red blood cells with carbon monoxide. This can lead to serious tissue damage, or even death.
