Vedclass · Accepted Answer

Hemoglobin binds with $CO$ instead of $O_2$,and the resulting product does not dissociate.

Vedclass · Answer

(D) Carbon monoxide $(CO)$ has a very high affinity for hemoglobin,approximately $200$ to $250$ times greater than that of oxygen $(O_2)$.When $CO$ is inhaled,it binds with hemoglobin to form carboxyhemoglobin $(HbCO)$.This binding is much more stable than oxyhemoglobin $(HbO_2)$,meaning the $CO$ does not easily dissociate from the hemoglobin.As a result,the oxygen-carrying capacity of the blood is significantly reduced,leading to tissue hypoxia and potentially death.
