Oxyhaemoglobin would not dissociate to supply ${O_2}$ to the tissue.

Vedclass · Answer

(C) The dissociation of oxyhaemoglobin into haemoglobin and ${O_2}$ depends on the partial pressure gradient of ${O_2}$ between the blood and the tissues.In normal physiological conditions,the partial pressure of ${O_2}$ $(pO_2)$ is high in the alveoli (respiratory surface) and low in the tissues,which facilitates the release of ${O_2}$ from oxyhaemoglobin to the tissues.If the ${O_2}$ concentration (and thus $pO_2$) in the tissue were as high as at the respiratory surface,there would be no partial pressure gradient.Without this gradient,oxyhaemoglobin would not dissociate,and ${O_2}$ would not be released to the tissues.

If ${O_2}$ concentration in tissue was almost as high as at the respiratory surface,what would happen?
