Hemoglobin unlike myoglobin showsa) Sigmoid curve of oxygen dissociationb) Positive cooperativityc) Hills coefficient of oned) None of above
High-Yield Explanation
Hb-O2 dissociation curve- Sigmoid shape
Co-operativity- Hb is a tetramer. If one molecule of O2 binds to the tetramer more easily if other O2 is already bound.
Hills coefficient of Hb- 2.8
