Binding of oxygen to haemoglobin reduces its affinity for carbon dioxide, which is known as: (A) Haldane effect, (B) Chloride shift, (C) Bohr effect, (D) Anion exchanger 1
Answer is A. Increase in carbon dioxide in the blood causes oxygento be displaced from the hemoglobin (the Bohr effect). The reverse is also true: binding of oxygen with hemoglobin tends to displace carbon dioxidefrom the blood. Indeed, this effect, called the Haldane effect, Ref: Guyton & Hall: Textbook of Medical Physiology page no:946
