WebbM. Berenbrink, in Encyclopedia of Fish Physiology, 2011 Abstract. The Bohr effect refers to the property of vertebrate hemoglobins (Hbs) whereby changes in pH affect the Hb- oxygen (O 2) affinity, supporting loading (in the lungs/gills) and unloading (in the tissues) of O 2 from Hb. The molecular mechanisms suggest that it evolved 3 times independently.
