Answer to Question 1

ANS: B
Erythrocyte concentrations of 2,3-DPG in banked blood decrease over time. After a week of storage, the 2,3-DPG level may be less than one-third of the normal value.

Answer to Question 2

ANS: A
The impact of changes in blood pH on hemoglobin affinity for O2 is called the Bohr effect. As shown in Figure 12-10, the Bohr effect alters the position of the HbO2 dissociation curve. A low pH (acidity) shifts the curve to the right, decreasing Hb affinity for O2 and thus O2 saturation.
