Question

Which does not effect oxyhaemoglobin dissociation curve?

• A. High $O_2$ and high haemoglobin
• B. Hign $O_2$ and low ${CO}_2$
• C. High body temperature
• D. High pH

Answer 1

The correct option is A High $O_2$ and high haemoglobin

The oxygen-haemoglobin dissociation curve shows the relationship between oxygen saturated haemoglobin and partial pressure of oxygen in blood giving a sigmoid curve.

Factors affecting this curve are:-

1. Temperature
   
2. pCO2
   
3. pH
   
4. 2,3-Bisphosphoglycerate

These factors alter the oxyhemoglobin dissociation curve.

High oxygen and haemoglobin level will simply show a sigmoid curve and will not affect the curve.

So, the correct answer is option A.
