Question

Which of the following conditions produces a favorable environment for hemoglobin to bind to oxygen? (Normal body temperature is <100°F;normal blood pH: 7.35-7.45. )
A)A body temperature of 102°F
B)A high 2,3-BPG concentration
C)A blood pH of 7.31
D)High PO₂

Quizplus · Accepted Answer

Hemoglobin binds to oxygen most favorably in conditions of high PO₂. The other factors listed can actually decrease hemoglobin's affinity for oxygen. A body temperature of 102°F can cause hemoglobin to denature and lose its ability to bind to oxygen, a high 2,3-BPG concentration can shift the oxygen-hemoglobin dissociation curve to the right, making it more difficult for hemoglobin to bind to oxygen, and a blood pH of 7.31 is slightly acidic, which can also cause the oxygen-hemoglobin dissociation curve to shift to the right, reducing hemoglobin's affinity for oxygen.
