http://hyperphysics.phy-astr.gsu.edu/hbase/Organic/hemo.html WebEach iron ion in the heme can bind to one oxygen molecule; therefore, each hemoglobin molecule can transport four oxygen molecules. An individual erythrocyte may contain about 300 million hemoglobin molecules, and therefore can bind to and transport up to 1.2 billion oxygen molecules (see Figure 18.7b).. In the lungs, hemoglobin picks up … WebAlthough the heme-bound iron can be in either the ferrous (Fe2+) or ferric (Fe3+) oxidation states, only the Fe2+ state is capable of binding oxygen. The iron ion can form two additional bonds, one on each side of the heme plane. These binding sites are called the fifth and sixth coordination sites.
