The binding of oxygen by hemoglobin is modulated by 2,3-bisphosphoglycerate (2,3-BPG). Indicate which of the following statements apply to this modulation. (Select all that apply.) Positive charges in the interior of hemoglobin form salt bridges with the negative charges on 2,3-BPG. The half-saturation Po, value for hemoglobin is dramatically increased when 2,3-BPG is present. The carboxy terminal nitrogens of the two a subunits of hemoglobin interact with the negative charges on 2,3-BPG. The half-saturation Po, value for hemoglobin is dramatically decreased when 2,3-BPG is present.
