Topic Question 6-ch5 Describe the molecular details of how Oxygen binds to the heme residue of myoglobin and hemoglobin. Also explain how they works for respiration. With O2 binding to Fe ; and pulls the Fe toward O2. →Conformation change Eventually T-> S conversion Myoglobin contains a Fe(II) cation bound to a heme group, which gives it the ability to bind to oxygen reversibly. Oxygen can bind to the heme residue of myoglobin due to the iron ion's interaction with six ligands. Hemoglobin Structure Animation Hemoglobin T R State HHMI
