Figure 46-4
Use the figure to answer the corresponding question(s) . Oxygen-hemoglobin dissociation curves at three different pH levels
-Which of the following statements would be true of Figure 46-4?

A) Hemoglobin would be 50% saturated at a
of 30 mm Hg at the highest pH.
B) Hemoglobin would be 50% saturated at a
of 25 mm Hg at the lowest pH.
C) At a
of 40 mm Hg, the hemoglobin for the pH 2 line would be 80% saturated.
D) At a lower pH, the oxygen dissociation curve is shifted to the right.
E) At a higher pH, the oxygen dissociation curve is shifted to the right.
