Question

Quizplus · Accepted Answer

Hemoglobin's oxygen-binding behavior is best described by the allosteric model, which is a combination of the sequential and concerted models. This model explains how the binding of oxygen to one subunit of hemoglobin increases the affinity of the remaining subunits for oxygen, a process known as cooperative binding.
