(b) When the relationship between the $\text{p}{{\text{O}}_{2}}$ and the percent saturation of haemoglobin is represented on a graph, then it is termed as oxygen - haemoglobin dissociation curve. A rise in $\text{pC}{{\text{O}}_{2}},{{\text{H}}^{+}}$ions (fall in $\text{pH}$ ), temperature and diphosphoglyceric acid raises the ${{p}_{50}}$ value and shifts the oxygen - dissociation curve to right
or vice versa.

Which of the following equation shows the role of carbonic anhydrase enzyme in the transport of carbon dioxide by blood?
(a) Oxygen dissociation curve describes the relation between the partial pressure of oxygen ( $x$-axis) and the haemoglobin saturation ( $y$-axis). Haemoglobin's affinity for oxygen increases as successive molecules of oxygen bind.
(b) When the relationship between the $\text{p}{{\text{O}}_{2}}$ and the percent saturation of haemoglobin is represented on a graph, then it is termed as oxygen - haemoglobin dissociation curve. A rise in $\text{pC}{{\text{O}}_{2}},{{\text{H}}^{+}}$ions (fall in $\text{pH}$ ), temperature and diphosphoglyceric acid raises the ${{p}_{50}}$ value and shifts the oxygen - dissociation curve to right
