Final answer:
The oxygen equilibrium curve will shift to the RIGHT when blood pH drops due to the Bohr Effect, as a lower, more acidic pH promotes oxygen dissociation from hemoglobin.
Step-by-step explanation:
The oxygen equilibrium curve will shift to the RIGHT when blood pH drops (known as the Bohr Effect).
This is because a lower, more acidic pH promotes oxygen dissociation from hemoglobin. As the level of carbon dioxide in the blood increases, more hydrogen ions are produced, which lowers blood pH. Thus, a decrease in blood pH causes the oxygen dissociation curve to shift to the right, indicating a higher affinity for oxygen.
