Haemoglobin combines with $CO$ instead of ${O_2}$ and the product cannot dissociate.

Vedclass · Answer

(B) Carbon monoxide $(CO)$ has approximately $210$ times more affinity for haemoglobin compared to oxygen $({O_2})$.When $CO$ is inhaled,it binds with haemoglobin to form a very stable compound called carboxyhaemoglobin.Because this bond is much stronger than the oxyhaemoglobin bond,the haemoglobin is unable to transport oxygen to the body tissues effectively.This leads to cellular hypoxia,which the body perceives as suffocation.

When a man inhales air containing a normal concentration of ${O_2}$ as well as $CO$,he suffers from suffocation because:
