Passage VII
The amount of O2 present in blood and tissues can be measured, in mm Hg, as the partial pressure of O2 (
). The percent saturation of Hb is the percent of hemoglobin in the blood that is bound with O2. Figure 1 shows the relationship between percent saturation of Hb and , at normal body conditions.
Figure 2 shows the relationship between percent saturation of Hb and , at different pHs. The pH of blood is affected by the partial pressure of CO2 ().
Figure 3 shows the relationship between percent saturation of Hb and , at different blood temperatures.
38. A researcher has claimed that the ability of Hb to bind with O2 at a given will decrease as temperature is increased. Do the data in Figure 3 support his claim?
Your Answer is
Correct Answer is J
Explanation
Look at figure 3, as the temperature rises, the percent saturation of Hb corresponding to the same abscissa is indeed getting smaller and smaller, so the statement in the question stem is correct
