Vedclass · Answer

(D) Haemoglobin $(Hb)$ is a respiratory pigment that carries gases in the blood.It binds with oxygen to form oxyhaemoglobin.However,the affinity of haemoglobin for carbon monoxide $(CO)$ is approximately $200$ to $250$ times greater than its affinity for oxygen $(O_2)$.When $CO$ is inhaled,it binds firmly with haemoglobin to form carboxyhaemoglobin,which is a very stable compound.This prevents haemoglobin from binding with oxygen,leading to tissue hypoxia and potentially fatal carbon monoxide poisoning.

Haemoglobin has the maximum affinity with which of the following?
