Which of the following would have the greatest accelerating effect on the dissociation of oxygen from hemoglobin?
A) Increased PO2
B) Decreased PCO2
C) Decreased PO2 and decreased PCO2
D) Decreased PO2 and increased PCO2

Question

Quizplus · Accepted Answer

Decreased PO2 and increased PCO2 both contribute to the rightward shift of the oxygen-hemoglobin dissociation curve, facilitating the release of oxygen from hemoglobin. This is known as the Bohr effect, where increased CO2 concentration and decreased oxygen partial pressure in tissues enhance oxygen unloading.
