Hemoglobin, the oxygen-transport protein, binds about 1.35 mL of oxygen per gram of the protein. The concentration of hemoglobin in normal blood is 150 g/L blood. Hemoglobin is about 95 percent saturated with O2 in the lungs and only 74 percent saturated with O2 in the capillaries. Calculate the volume of O2 released by hemoglobin when 171 mL of blood flows from the lungs to the capillaries.
