Question

Quizplus · Accepted Answer

BPG (2,3-bisphosphoglycerate) binds to hemoglobin and stabilizes it in its deoxygenated form, making it less likely to bind oxygen. Removing BPG shifts the oxygen binding curve of hemoglobin to the left, making it more like that of myoglobin, which has a higher affinity for oxygen and does not bind BPG.
