Question

Quizplus · Accepted Answer

The Hill plot is used to describe cooperative binding in proteins such as hemoglobin. It shows that the binding affinity of hemoglobin for oxygen increases with each oxygen molecule that binds. Specifically, the fourth oxygen molecule binds with approximately 100-fold greater affinity than the first, illustrating the cooperative nature of oxygen binding to hemoglobin.
