How does partial pressure and concentration of oxygen affect hemoglobin and oxygen exchange?

Partial pressure plays a significant role in the binding of oxygen and dissociation from heme which is a binding iron protein found in hemoglobin. The ability of an oxygen molecule to develop an affinity for heme increases as more oxygen molecules are bound. Thus as the partial pressure of oxygen increases, one can find a greater number of oxygen molecules bound by heme. Conversely, the lower the partial pressure of oxygen, less oxygen molecules are bound to heme.

Hope this helps!
