Vedclass · Answer

(A) The oxygen-haemoglobin dissociation curve is sigmoid in shape,representing the relationship between the partial pressure of oxygen $(pO_2)$ and the percentage saturation of haemoglobin with oxygen.Factors like an increase in temperature,decrease in $pH$,or increase in $pCO_2$ shift the curve to the right (Bohr effect),indicating a lower affinity of haemoglobin for oxygen.Conversely,when the temperature decreases or $pH$ increases,the affinity of haemoglobin for oxygen increases,causing the curve to shift to the left and become more steep.

When temperature decreases,the oxyhaemoglobin dissociation curve will become:
