Web29 nov. 2024 · The Bohr effect causes the muscles and tissues to release more oxygen when CO2 levels rise. This helps deliver oxygen to metabolizing tissue such as skeletal muscle, where it is needed most. The Bohr effect is a result of the effect carbon dioxide has on hemoglobins affinity for oxygen. WebThe 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. In contrast, a higher, or more …

WebAbstract: The Bohr effect in Hb, which refers to the dependence of the oxygen affinity on the pH, plays an important role in its cooperativity and physiol. function. The dominant contribution to the Bohr effect arises from the difference in the pKa values of His residues of the unliganded (deoxy) and liganded (carbonmonoxy) structures.
