Question

5. Under normal physiological conditions, hemoglobin is half saturated with O2 at 26 torr, and the Hill coefficient nn = 2.8. What is the degree of saturation when the partial pressure of O2 in the tissue capillaries falls to 33 torr during gentle walking? A. 0.34 B. 0.41 C. 0.56 D. 0.66 E. 1.00

Answer 1

Question 5: The correct answer is D. 0.66.

Explanation:

Question 50 To solve this problem, we can use the following formula, where, y = The fractional satunation of hemoglobin PO, = The partial pressure of O, Piso = The partial pressure of Og at which hemoglobin is half saturated. n = The Hill coefficient. 30, hene, pO2 = 33 town Piso = 26 tonn n = 2.8 y = ? => y = 2(1-4) => y = 2- 24 = 4+2y=2 => y = = = 0.66 .y=0.66 (Answen) ... The degree of saturation of hemoglobin is 0.66 when the pO2 is 33 tonn.
