Vedclass · Answer

(A) The dissociation of oxyhaemoglobin into oxygen and deoxyhaemoglobin is primarily determined by the partial pressure of oxygen $(P_{O_2})$.In metabolically active tissues,the $P_{O_2}$ is significantly lower compared to the blood.According to the oxygen-haemoglobin dissociation curve,a decrease in $P_{O_2}$ promotes the release of oxygen from haemoglobin.Therefore,oxyhaemoglobin dissociates into oxygen and deoxyhaemoglobin at low $O_2$ pressure in the tissues.
