Hemoglobin is 50% saturated with oxygen when pO2 = 26 torr. If hemoglobin exhibited hyperbolic binding (as myoglobin does) with 50% saturation at 26 torr, what would be the fractional saturation when pO2 = 30 torr? What would be the fractional saturation when pO2 = 100 torr? What does this tell you about the physiological importance of hemoglobin’s sigmoidal oxygen-binding curve? Be sure to show your work for full credit.
