Oxygen binds to haemoglobin at the lung surface and dissociates at the tissues. Justify.

For the formation of oxyhaemoglobin, the factors required such as high pO2, low pCO2, low concentration of H+ ions and low temperature are maintained in the alveoli. Hence, the binding of oxygen with haemoglobin at lung surfaces is faster.



Low pO2, high pCO2, high H+ ion concentration and high temperature are the factors found in tissues which always favour the dissociation of oxygen.
