Essential Biochemistry - Chemistry Of Hemoglobin (Section 2 - No. 46)
What is the significance of the sigmoidal shape of the oxygen-hemoglobin dissociation curve?
It indicates a low oxygen-binding affinity.
It reflects the cooperative binding of oxygen to hemoglobin.
It indicates that hemoglobin is not affected by pH.
It represents a simple binding process without cooperativity.
Explanation
