With time, blood stored in a blood bank tends to become relatively depleted of 2,3- diphosphoglycerate (2,3-DPG). What effect does this have on the hemoglobin-oxygen dissociation curve?
(A) Shifts the curve to the left, so that the hemoglobin has a decreased oxygen affinity
(B) Shifts the curve to the left, so that the hemoglobin has an increased oxygen affinity
(C) Shifts the curve to the right, so that the hemoglobin has a decreased oxygen affinity
(D) Shifts the curve to the right, so that the hemoglobin has an increased oxygen affinity
(E) Does not change the dissociation curve
