Question

The oxygen - haemoglobin dissociation curve will show a right shift in case of

• A. High $pC{O}_2$
• B. High $p{O}_2$
• C. Low $pC{O}_2$
• D. Less $H^{+}$ concentration

Answer 1

The correct option is A High $pC{O}_2$

An increase in $\left[pC{O}_2\right]$, $\left[H^{+}\right]$, and temperature, can lead to the right shift of the oxygen-haemoglobin dissociation curve. The increase in $\left[pC{O}_2\right]$, $\left[H^{+}\right]$ causes a decrement in the pH which leads to the change in oxygen-haemoglobin binding.

So, the correct answer is (A)
