If the O₂-binding curves were plotted for adult hemoglobin under the following conditions, which curve would be to the right of all the others?

Question

A high level of 2,3-bisphosphoglyceric acid (2,3-BPG) stabilizes the taut (T) state of hemoglobin, which has a lower affinity for oxygen. A low pH also stabilizes the T state. Both of these conditions shift the binding curve to the right, indicating a lower affinity for oxygen. The combination of a low pH and high 2,3-BPG concentration is found in conditions such as exercise or high altitude, where the tissues need more oxygen to compensate for the lower oxygen availability. Therefore, the curve with the most significant shift right would be D, pH 7.2 with much 2,3-bisphosphoglyceric acid.
