Q. Which of the following will shift the oxy-haemoglobin dissociation curve to right?

NTA AbhyasNTA Abhyas 2022

Solution:

Oxygen dissociation curve
When percentage saturation of haemoglobin with $O_{2}$ is plotted against the $p O_{2}$ , a sigmoid curve is obtained which is termed as Oxygen dissociation curve. Utility: This curve is highly useful in studying the effects of various factors (like $p C O_{2}$ , $H^{+}$ concentration, etc.) on the binding of $O_{2}$ with haemoglobin. Factors that are favourable in the tissues for the dissociation of oxyhaemoglobin shifting the curve towards the right: Low $p O_{2}$ , high $p C O_{2}$ , greater $H^{+}$ concentration and higher temperature.
