Explanation:
Detailed explanation-1: -Oxyhemoglobin travels through the bloodstream to cells, where it breaks down to form hemoglobin and oxygen. The oxygen then passes into cells. So, oxyhemoglobin is unstable because, it readily gives up oxygen to body cells.
Detailed explanation-2: -The dissociation of oxygen from oxyhaemoglobin is favoured by: Low partial pressure of oxygen (O2) in tissues. High partial pressure of carbon dioxide (CO2) in tissues. High H+ ion concentration, i.e, low pH in blood.
Detailed explanation-3: -In the blood stream it combines with haemoglobin to form oxyhaemoglobin. This oxygen is taken inside the cells and carbondioxide is released.
