Vedclass · Answer

(B) Hemoglobin is a metalloprotein found in red blood cells. The iron atom in the heme group of hemoglobin is present in the ferrous state,which is $Fe^{2+}$. This state allows the iron to bind reversibly with oxygen to form oxyhemoglobin. If the iron were in the $Fe^{3+}$ (ferric) state,it would form methemoglobin,which cannot bind oxygen effectively.
