In presence of carbon monoxide, haemoglobin loses its oxygen-carrying capacity causing oxygen starvation of body cells-explain

Text Solution

Verified by Experts

Carbon monoxide has a strong affinity for haemoglobin. This gas combines with haemoglobin to form highly stable carboxyhaemoglobin
`Hb+CO hArr HbCO`
consequently availability of oxygen in the body-cells decreases, because haemoglobin fails to carry oxygen nacessary for the life process to continue. So carbon monoxide present in excess may sometimes cause death.
