Question

How are the Bohr/Haldane effects adaptive?

a. they cause O2 to be delivered from exercising tissues to the lungs

b. they cause hemoglobin to develop a low affinity for O2 at precisely the tissues that require oxygen the most-the ones producing CO2

c. they cause hemoglobin to have a decreased affinity for CO2 in precisely the regions where CO2 must be delivered from the body, the lungs

d. they cause hemoglobin to substitute binding of O2 for CO2 in its heme groups, in exercising tissues with low Ph

e. b and c

Explanation / Answer

According to bohr effects when the hemoglobin is oxygenated the co2 dissociation curves shift to right i.e,the blood begins to lose some co2 as it becomes oxygenated.

Loading of oxyegen to the blood causes unloadin of co2,a phenomena seen at lung level.so the correct ans . Is option (C)
