Quizplus · Accepted Answer

The Bohr effect describes how a decrease in pH (or an increase in CO2 concentration) leads to a decrease in the affinity of hemoglobin (Hb) for oxygen (O2), which in turn causes a decrease in Hb saturation for a given partial pressure of oxygen (PO2). This means that under more acidic conditions (lower pH), hemoglobin releases more oxygen to the tissues.
