Write about Haldane effect

Write about Haldane effect. How does Haldane effect and Bohr effect complement each other?

Haldane effect states that binding of oxygen with haemoglobin tends to displace C02 from the blood. It is quantitatively more important in promoting ${{CO}_{2}}$ transport than the Bohr effect in 02 transport. Thus, Haldane effect and Bohr effect complement each other.
