Each hemoglobin molecule
WebNational Center for Biotechnology Information Web2/ Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind one oxygen molecule. 3/ Molecular oxygen binds reversibly to the Fe(II)Fe(II) atom in heme. 4/ By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron. 5/ Each iron atom can form six coordination bonds.
