Which of the following will shift the oxy-haemoglobin dissociation curve to right?
Options
- AIncreased CO 2
- BDecreased acidity
- CIncreased pH
- DDecreased temperature.
Correct answer
A. Increased CO 2
Step-by-step 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
