Physiologic conditions in the body that can decrease hemoglobin's oxygen affinity include:

Question

Quizplus · Accepted Answer

Increased body temperature can cause a decrease in hemoglobin's oxygen affinity, which is known as the Bohr effect. This is because increased temperature promotes the release of oxygen from hemoglobin to the tissues that need it.

Answer: D
 The presence of abnormal hemoglobins, such as sickle cell hemoglobin, can cause a decrease in oxygen affinity due to changes in the structure of the protein. This can lead to oxygen not binding as well to the hemoglobin molecule, which can be detrimental to oxygen transport in the body.

Therefore, the correct answer is C and D.
