(b) The diagram on the right illustrates the change in the p50 (partial pressure of O2 required to achieve 50% saturation) of hemoglobin and the 2,3-bis-phosphoglycerate (BPG) concentration in the erythrocytes of a person who spent 6 days hik- ing in the Andes Mountains of Peru. As the hiker climbs to higher and higher altitudes, the atmos- pheric pressure, including the partial pressure of O2, decreases. Yet the p50 increases, making it less favorable to achieve saturation of the hemo- globin. Explain.
