The oxygen dissociation curve of myoglobin & hemoglobin is different due to

The lack of cooperative binding is reflected in myoglobin dissociation curve.,a rectangular hyperbola is obtained. In the case of Hb, a sigmoid curve is obtained. A leftward shift in myoglobin O2 binding curve when compared to Hb demonstrates a higher affinity for O2 and thus promotes a orable transfer of O2 from Hb in the blood.Ref: Ganong&;s Review of medical physiology, 24th edition.Pg no. 643
