Which of the following will decrease the affinity of hemoglobin for oxygen?
A)decreased pH,decreased temperature,or decreased 2,3-DPG
B)decreased pH,increased temperature,or increased 2,3-DPG
C)increased pH,increased temperature,or decreased 2,3-DPG
D)increased pH,decreased temperature,or increased 2,3-DPG

Decreased pH (i.e., acidic conditions), increased temperature, and increased levels of 2,3-diphosphoglycerate (2,3-DPG) all decrease the affinity of hemoglobin for oxygen. This means that hemoglobin is less likely to bind to oxygen molecules under these conditions. Therefore, only option B includes all three factors that decrease the affinity of hemoglobin for oxygen.
