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

A

high `pCO_(2)`

B

high `pO_(2)`

C

low `pCO_(2)`

D

less `H^(+)` concentration

Text Solution

Verified by Experts

The correct Answer is:
a
A sigmoid curve obtained when percentage saturation of haemogblobin with `O_(2)` is plotted against the `pO_(2)`.

The oxygen haemoglobin dissociation curve is shifted to right under following condition.
(i) Decrease in partial pressure ef oxygen.
(ii) Increase in partial pressure of carbonoxide.
(iii) Increase in hydrogen concentration.
(iv) Decrease in pH activity.
(v) Increased body temperature.
