CAIE A-Level Biology AS 8.2.6 Bohr Shift and Its Importance Questions question 1
The diagram shows the effect of three different concentrations of carbon dioxide on the oxygen dissociation curve for human haemoglobin.
Which effect does increasing carbon dioxide concentration have on haemoglobin?
A
It makes haemoglobin less efficient at taking up oxygen and less efficient at releasing oxygen.
B
It makes haemoglobin less efficient at taking up oxygen and more efficient at releasing oxygen.
C
It makes haemoglobin more efficient at taking up oxygen and less efficient at releasing oxygen.
D
It makes haemoglobin more efficient at taking up oxygen and more efficient at releasing oxygen.
