Vedclass · Answer

(D) If a person breathes air containing a normal amount of oxygen $(21 \%)$ and a small amount of carbon monoxide,they suffer from suffocation because haemoglobin combines with carbon monoxide to form a stable compound known as carboxyhaemoglobin.The affinity of haemoglobin for carbon monoxide is about $250$ times greater than its affinity for oxygen.Even $0.1 \%$ of carbon monoxide can block $50 \%$ of the body's haemoglobin,significantly decreasing the oxygen-carrying capacity of the blood.This condition,which leads to oxygen deprivation in tissues,is called hypoxia.
