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.

During oxygen transport,the oxyhaemoglobin at the tissue level liberates oxygen to the cells because in tissue:
