Oxygen Binding to Myoglobin and Hemoglobin. (a) The Fe 2+ ion in deoxymyoglobin is high spin, which makes it too large to fit into the “hole” in the center of the porphyrin. (b) When O 2 binds to deoxymyoglobin, the iron is converted to low-spin Fe 3+, which is smaller, allowing the iron to move into the plane of the four ...
