Question

the haldane effect describe the increase in the affinity of homoglobin for CO2 in the presence of a lowered

Answer 1

The Haldane effect is the activity of oxygenation of blood in the lungs which displaces carbon dioxide from the haemoglobin by removing the carbon dioxide. Due to this displacement of carbon dioxide, oxygenated blood has lesser affinity for carbon dioxide and then, the Haldane effect explains the ability to carry increased amounts of carbon dioxide by the haemoglobin in deoxygenated state. Thus, high concentration of carbon dioxide facilitates the dissociation of oxyhaemoglobin. The majority of CO2 in the blood will be in the form of bicarbonate and only very small amount of it is dissolved as carbon dioxide and the remaining gets bound to the haemoglobin. Hence, the Haldane effect describes the increase in affinity of haemoglobin for carbon dioxide in the presence of lowered carbon dioxide.
