Vedclass · Answer

(D) At the tissue level,cellular respiration consumes oxygen and produces carbon dioxide. Consequently,the partial pressure (tension) of $O_2$ is low,and the partial pressure (tension) of $CO_2$ is high in the tissues compared to the blood. According to the Bohr effect,high $CO_2$ concentration and low $O_2$ tension shift the oxygen-haemoglobin dissociation curve to the right,facilitating the dissociation of oxygen from oxyhaemoglobin. Therefore,oxyhaemoglobin releases oxygen to the cells.
