Question

The Bohr effect describes the tendency for hemoglobin to more readily unload oxygen under which conditions?

a. increased pH and decreased PCO2
b. decreased pH and increased PCO2
c. decreased pH and PCO2
d. increased pH and PCO2

Answer 1

b. decreased pH and increased PCO2

Step-by-step explanation:

a lower and more acidic pH will lead to dissociation of oxygen form the hemoglobin.

the increase in PCO2 will cause a decrease in pH , so the affinity of heamoglobin for oxygen will decrease and improve the unloading of oxygen.
