Q). The presence of hemoglobin in normal arterial blood increases its oxygen concentration approximately how many times? A. 10 B. 30 C. 50 D. 70 E. 90 Answer: D. Normal arterial blood has a Po2 of about 100 mm Hg. The concentration of oxygen in the absence of hemoglobin is the dissolved oxygen, which is 100 × 0.003, or 0.3 ml 02.100 ml-1 blood. However, normal arterial blood contains about 15 g.100 ml-1 of hemo- globin, and each gram can combine with 1.39 ml O2. Since the oxygen saturation of normal arterial blood is about 97%, the total oxygen con- centration is given by (1.39 × 15 × 97/100) + 0.3 ml 02.100 ml-1 blood. This is about 20.5 as opposed to the dissolved oxygen concentration of 0.3 ml 02.100 ml-1 blood. Therefore, the presence of hemoglobin increases the oxygen concentration about 70 times.

Which is/are false? a. Carbaminohemoglobin is hemoglobin bound to carbon dioxide b. In the lungs, the oxyhemoglobin saturation curve undergoes a 'left shift' c. At a PO2 of 10 mmHg, there is more deoxyhemoglobin in blood that oxyhemoglobin d. Higher temperatures and lower pH cause hemoglobin to bind more readily with oxygen than in conditions of lower temperatures and higher pH
