When the blood passes through the lungs, CO₂ is expelled and the hemoglobin picks up oxygen. Place the following steps in the correct order (1 = first thing to happen), assuming that it is the decreased [CO₂] during exhalation that initiates the transition. Carbonic anhydrase works to restore the CO₂/bicarbonate equilibrium, reducing the [H+] The T-state is less stabilized. Oxygen binds to the hemoglobin. Protons dissociate from the hemoglobin.
