1 A) increases. B) does not change. C) decreases. 2 A) a large amount of oxygen is bound to hemoglobin. B) a small amount of oxygen is bound to hemoglobin. C) no oxygen is bound to hemoglobin. D) nothing with respect to the amount of oxygen bound to hemoglobin. 3 A) acidic. B) neutral. C) alkaline. 4 A) moves the oxygen dissociation curve to the left. B) moves the oxygen dissociation curve to the right. C) has no effect on the oxygen dissociation curve. 5 A) Blood with a lower pH has a lower transmittance value (‘color'). B) Blood with a lower pH has the same transmittance value (‘color') as blood without DPG. C) Blood with a lower pH has a higher transmittance value (‘color'). 6 A) Blood with a lower pH has more oxygen bound to hemoglobin. B) Blood with a lower pH has the same amount of oxygen bound to hemoglobin. C) Blood with a lower pH has less oxygen bound to hemoglobin. 7 A) decreases the amount of bound oxygen; i.e., hemoglobin releases more oxygen to the tissues. B) does not change the amount of bound oxygen bound; i.e., the amount of oxygen released is constant. C) increases the amount of bound oxygen bound; i.e., hemoglobin releases less oxygen to the tissues. 8 A) lactic acid, which can move into the interstititial fluid and then into the plasma. B) carbon dioxide, which reacts with water to form hydrogen and bicarbonate ions. C) both of the above options are true. 9 A) moves the oxygen dissociation curve to the left. B) has no effect on the oxygen dissociation curve. C) moves the oxygen dissociation curve to the right. 10 A) less oxygen is released, which leaves more oxygen bound to hemoglobin. B) more oxygen is released, which leaves more oxygen bound to hemoglobin. C) less oxygen is released, which leaves less oxygen bound to hemoglobin. D) more oxygen is released, which leaves less oxygen bound to hemoglobin.
