WebThe pH of the blood is another factor that influences the oxygen–hemoglobin saturation/dissociation curve (see Figure 2). The Bohr effect is a phenomenon that arises from the relationship between pH and oxygen’s affinity for hemoglobin: A lower, more acidic pH promotes oxygen dissociation from hemoglobin.
