Question

Quizplus · Accepted Answer

All of the choices affect the release of oxygen from hemoglobin. The partial pressure of oxygen, temperature, acidity, and carbon dioxide in the tissue all play a role in the release of oxygen from hemoglobin. For example, as the partial pressure of oxygen decreases, hemoglobin releases more oxygen. As temperature increases, hemoglobin releases more oxygen. As acidity increases (i.e. pH decreases), hemoglobin releases more oxygen. And as carbon dioxide levels increase, hemoglobin releases more oxygen.
