Question : When partial pressure of CO_(2) rises, the oxygen dissociation curve of haemoglobinat37^(@)C will :

Answer»

REMAIN unchanged
become irregular
shift TOWARDS left
shift towards right

Solution :Rise in `pCO_(2)` will leads to lowering of `pO_(2)` and thus % saturation of haemoglobin with oxgen willbe LESSER there by shiftingthe oxygen dissociation curveof haemoglobin to right .
