Vedclass · Answer

(D) The transport of oxygen involves the reversible binding of oxygen with haemoglobin $(Hb)$ to form oxyhaemoglobin $(HbO_{2})$.In the lungs,the high partial pressure of oxygen $(pO_{2})$ and low partial pressure of carbon dioxide $(pCO_{2})$ favor the association of oxygen with haemoglobin: $Hb + O_{2} \rightarrow HbO_{2}$.In the tissues,the low partial pressure of oxygen $(pO_{2})$ and high partial pressure of carbon dioxide $(pCO_{2})$ favor the dissociation of oxyhaemoglobin to release oxygen: $HbO_{2} \rightarrow Hb + O_{2}$.Therefore,the correct reversible equation is $Hb + O_{2} \rightleftharpoons HbO_{2}$,where association occurs in the lungs and dissociation occurs in the tissues. Option $D$ correctly represents this process.
