In which of these PO₂ environments would hemoglobin release its O₂ most readily?

Question

Quizplus · Accepted Answer

As per the Bohr effect, the affinity of hemoglobin for oxygen decreases with decreasing pH and increasing CO2 levels. In environments where the partial pressure of oxygen (PO2) is low, such as at 30 mm Hg, hemoglobin releases its oxygen more readily. This is because at a lower PO2, the oxygen gradient is steeper, and the oxygen-hemoglobin bond is weaker. Thus, hemoglobin is able to release its oxygen more readily in environments with lower PO2.
