Discussion

17261.	Question : Haldane effect plays more important role in promoting carbon dioxide tranport than that of the Bhr's effect in promoting oxygen trasnport because
Answer» oxyhaemoglobin is a stronger acid which donates HYDROGEN ion `(H^(+))` which in turn displace carbone dioxide from blood carbaminohaemoglobin is a stronger acid which spilts into hydrogen ion `(H^(+))` and bicarbonate `(HCO_(3)^(-))` carbon dioxide reacts with water to form CARBONIC acid that lowers the pH in tissue carbon dioxide is less soluble in venous blood than in arterial blood. Solution :The degree of oxygenation of blood markedly affects the amount of `CO_(2)` transported in blood. The lower the `PO_(2)` and the haemoglotion saturation with `O_(2)`. the more the `CO_(2)` that can be carried in the blood. This phenomenon, is called the Haldane effect. It depicts the greater ability of reduced haemoglobin to form carbaminohaemoglobin and to buffer `H^(+)` by combing with it. In the pulomonary circulation, uptake of `O_(2)` faciliates the release of `CO_(2)` from the pulmonary blood. The `CO_(2)` transport than the Bohr effect in promoting `O_(2)` transport its results from the SIMPLE fact that combination of `O_(2)` with become a stronger acid. This in turn displaces `CO_(2)` form the blood.
