Question 1 of 5
What type of curve is obtained when the percentage saturation of hemoglobin with oxygen is plotted against the partial pressure of oxygen?
Correct Answer: C
Rationale: When the percentage saturation of hemoglobin with oxygen is plotted against the partial pressure of oxygen (pO₂), a sigmoid curve is obtained. This curve is known as the Oxygen Dissociation Curve and illustrates the relationship between the amount of oxygen bound to hemoglobin and the pO₂. The sigmoid shape of the curve reflects the cooperative binding and release of oxygen by hemoglobin.
