Which of These Is Demonstrated by the Oxygen-Hemoglobin Dissociation Curve

question 86

Multiple Choice

Which of these is demonstrated by the oxygen-hemoglobin dissociation curve?

• A) The greater the P_O2 of the blood, the greater the dissociation of O₂ from hemoglobin.
• B) At normal resting systemic arterial P_O2 , hemoglobin is almost 100% saturated with oxygen.
• C) At normal resting systemic venous P_O2 , only about 75% of the hemoglobin is in the form of deoxyhemoglobin.
• D) More additional oxygen binds to hemoglobin when going from a P_O2 of 60 to 100 mmHg, than is added when going from a P_O2 of 40 to 60 mmHg.
• E) As P_O2 increases, the saturation of hemoglobin with oxygen increases linearly.
