In addition to O, binding, changes in other chemical conditions can result in hemoglobin changes.
pH is one of those factors. It can be understood by reaction #1. Red blood cells have the enzyme
Carbonic Anhydrase which catalyzes reaction #2. Using the two reactions explain how pH contributes
to the transfer of O2 from the lungs to the tissues.
H-Hb* + O2 Hb-O2 + H*
Reaction #1
CO2(aq) + H2O= H* + HCO3
Reaction #2

a. Generally, raise the affinity of Hb for O2
b. Generally, lower the affinity of Hb for O2
