Solution

The correct option is D pH
pH

The decrease in pH will result in an increase of $H^{+}$ ions and the oxyhaemoglobin curve will be shifted to the right side.

It will result in the dissociation of $O_{2}$ from oxyhaemoglobin.

This dissociation of oxygen will result in the decrease of $P_{50}$ .

Now it requires more oxygen concentration to reach the 50% saturation level.

Hence, an increase in $P_{50}$ of an oxyhaemoglobin curve would result from a decrease in pH.

Final answer: (1) pH
