Carboxyhaemoglobin

Vedclass · Answer

(C) Carbon monoxide $(CO)$ has a very high affinity for haemoglobin,approximately $200-250$ times greater than that of oxygen $(O_2)$.When $CO$ binds to haemoglobin,it forms a stable compound known as carboxyhaemoglobin.This binding prevents haemoglobin from transporting oxygen to the tissues,leading to hypoxia and potentially fatal carbon monoxide poisoning.Therefore,the correct option is $C$.

Carbon monoxide combines with haemoglobin to form . . . . . . .
