Choose the correct answers based on the oxygen binding curves shown below for beaver hemoglobin measured at two pH values. Assume that the blood leaving the lungs of the beaver has pO2 = 100 torr and pH = 7.6. Assume that after a beaver has been busy building dams all day, the blood leaving the actively respiring muscle tissue has pO2 = 20 torr and pH = 7.2.

Question

Please proper Explain your answer 

Choose the correct answers based on the oxygen binding curves shown below for beaver hemoglobin measured at two pH values. Assume that the blood leaving the lungs of the beaver has pO2 = 100 torr and pH = 7.6. Assume that after a beaver has been busy building dams all day, the blood leaving the actively respiring muscle tissue has pO2 = 20 torr and pH = 7.2. Beaver Hemoglobin YO2 1 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 0 20 pH 7.6 40 60 p02 (torr) 80 pH 7.2 100 120 Hb in the blood leaving the lungs is about 99% saturated with oxygen. Hb in the blood leaving actively respiring muscle tissue is about 10% saturated with oxygen. Based on the above curves, each mole of oxygen binding sites in Hb is delivering about 0.49 moles of oxygen from the lungs to the muscles. Hb in the blood leaving actively respiring muscle tissue is about 50% saturated with oxygen. O Based on the above curves, each mole of oxygen binding sites in Hb is delivering about 0.89 moles of oxygen from the lungs to the muscles.
