Essential Biochemistry - Chemistry Of Hemoglobin (Section 3 - No. 31)
What is the significance of the sigmoidal shape of the oxygen-hemoglobin dissociation curve?
It reflects the cooperative binding of oxygen to hemoglobin.
It indicates a low oxygen-binding affinity.
It shows the influence of pH on oxygen binding.
It means that oxygen binds reversibly to the heme.
Explanation
The sigmoid shape reflects cooperative binding and influence of pH.
