Iron is incorporated into protoporphyrin IX in the mitochondria of a developing red blood cell (RBC)to form heme.Oxygen binds reversibly to the iron in heme provided that iron is in the ferrous (divalent,reduced)state.Globin chains are part of the hemoglobin molecule;four of them exist per molecule,each containing a heme group.Methemoglobin is hemoglobin in which the iron is oxidized to the ferric (trivalent)form;it cannot bind oxygen.
