In blood: Respiration. …bind oxygen is called the Bohr effect: when pH is low, hemoglobin binds oxygen less strongly, and when pH is high (as in the … WebThe Bohr effect. The Bohr effect is not strictly related to CO 2 transport but is the reverse of the Haldane effect. The Bohr effect refers to the reduction in affinity of haemoglobin for oxygen in the presence of a reduction in pH or an increase in CO 2.This phenomenon allows offloading of oxygen at the tissues where the pH is lower as CO 2 is produced there.
