Vedclass · Answer

(A) Hemoglobin has a significantly higher affinity for carbon monoxide $(CO)$ compared to oxygen $(O_2)$.Specifically,the affinity of hemoglobin for $CO$ is approximately $200$ to $250$ times greater than its affinity for $O_2$.When $CO$ is inhaled,it binds to hemoglobin to form carboxyhemoglobin,which prevents oxygen from binding to the hemoglobin,leading to tissue hypoxia and potentially fatal poisoning.
