What role does carbonic anhydrase play in the cycle of hemoglobin from lungs to tissues?

Carbonic anhydrase catalyzes the conversion of CO2 and water to carbonic acid, affecting pH and oxygen release.

Carbonic anhydrase binds oxygen to hemoglobin in the lungs.

Carbonic anhydrase releases hydrogen ions in the tissues.

Carbonic anhydrase has no role in hemoglobin's cycle.
