Question

Quizplus · Accepted Answer

The Bohr shift on the oxygen-hemoglobin dissociation curve is caused by changes in pH, which are often induced by changes in carbon dioxide concentration. As carbon dioxide increases in the blood, it reacts with water to form carbonic acid, which lowers the pH of the blood, making it more acidic. This decrease in pH causes a rightward shift of the oxygen-hemoglobin dissociation curve, resulting in more oxygen being released from hemoglobin for a given partial pressure of oxygen. This is known as the Bohr shift.
