Vedclass · Answer

(C) At the tissue level,the partial pressure of oxygen $(pO_2)$ is low due to continuous metabolic consumption of oxygen by the cells.Conversely,the partial pressure of carbon dioxide $(pCO_2)$ is high due to cellular respiration.According to the oxygen-haemoglobin dissociation curve,a low $pO_2$ and high $pCO_2$ (Bohr effect) facilitate the dissociation of oxygen from oxyhaemoglobin.Therefore,oxyhaemoglobin releases oxygen to the tissues where it is needed for metabolic processes.

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