Vedclass · Answer

(B) The transport of oxygen in the blood is primarily carried out by hemoglobin $(Hb)$.$CO$ (Carbon monoxide) has a very high affinity for hemoglobin (about $200-250$ times more than $O_2$),forming carboxyhemoglobin,which prevents oxygen transport.$NO$ (Nitric oxide) also binds to hemoglobin and can interfere with oxygen transport.$SO_2$ (Sulfur dioxide) and $SO_3$ (Sulfur trioxide) are respiratory irritants that can cause inflammation in the respiratory tract,but they do not directly bind to hemoglobin to inhibit oxygen transport in the same manner as $CO$ or $NO$.Among the given options,$SO_3$ is the substance that does not directly inhibit the transport of oxygen by binding to hemoglobin.

Which of the following substances does not inhibit the transport of oxygen in the blood?
