Bohr Effect: How CO₂ and pH Affect O₂ Binding

What is the Bohr effect?

The Bohr effect is the decrease in hemoglobin’s affinity for oxygen when carbon dioxide levels rise or blood pH drops, promoting oxygen release to active tissues.

What are the Bohr and Haldane effects?

The Bohr effect describes how CO₂ and low pH reduce hemoglobin’s oxygen affinity, aiding oxygen release. The Haldane effect explains how oxygen binding in the lungs helps release carbon dioxide from blood.

What is the Bohr effect in A-level Biology?

In A-level Biology, the Bohr effect refers to how increased CO₂ or lower pH in tissues causes hemoglobin to release more oxygen, shown by a rightward shift in the oxygen dissociation curve.
