iron
yes
The iron containing part of hemoglobin is the 'heme' molecule.
The part of the blood that is responsible for carrying oxygen is hemoglobin. The hemoglobin binds to oxygen in the alveoli of the lungs. Then the hemoglobin releases the oxygen at the cells. The part of the hemoglobin molecule that is directly responsible for carrying the oxygen is the iron ion in the center of the molecule's structure. The iron ion changes from a Fe +2 ion to a Fe +3 when carrying the oxygen. Then the hemoglobin reaches the cell, the iron ion decomposes back to the more stable Fe +2 state, replacing the oxygen with a water molecule.
