A physiology student tries to distinguish the Bohr effect from the Haldane effect. Both involve hemoglobin and gas transport but describe different relationships. Which combination best contrasts these two effects?

The Bohr effect describes how rising CO2 and falling pH decrease hemoglobin's affinity for O2, promoting O2 unloading at the tissues; the Haldane effect describes how deoxygenated hemoglobin binds CO2 more readily, promoting CO2 pickup at the tissues Both effects describe the same phenomenon: that high pH increases O2 binding to hemoglobin The Bohr effect occurs only in the lungs; the Haldane effect occurs only in the tissues The Bohr effect describes CO2 binding to hemoglobin, while the Haldane effect describes O2 binding to hemoglobin
