The Bohr Shift on the Oxygen-Hemoglobin Dissociation Curve is Produced

Question

The Bohr shift on the oxygen-hemoglobin dissociation curve is produced by changes in
A) the partial pressure of oxygen.
B) the partial pressure of carbon monoxide.
C) hemoglobin concentration.
D) temperature.
E) pH.

Accepted Answer

The Bohr shift is a rightward shift in the oxygen-hemoglobin dissociation curve due to decreased pH (or increased acidity). This shift is advantageous to tissues since they produce more carbon dioxide and acid, thus favoring the unloading of oxygen by hemoglobin.
