It reduces the oxygen-carrying capacity of hemoglobin

Vedclass · Answer

(C) $CO$ (Carbon monoxide) is significantly more toxic than $CO_2$ (Carbon dioxide) because it has a much higher affinity for hemoglobin than oxygen does.When $CO$ is inhaled,it binds to hemoglobin to form carboxyhemoglobin.This binding is much stronger and more stable than the binding of oxygen to hemoglobin.As a result,the amount of hemoglobin available to transport oxygen to the body's tissues is drastically reduced,leading to tissue hypoxia and potentially fatal consequences.
