NEET Biology question

In the tissues, high concentrations of carbon dioxide

(A)increases the affinity of haemoglobin to both oxygen and hydrogen
(B)increases the affinity of haemoglobin to oxygen but decreases its affinity to hydrogen
(C)decreases the affinity of haemoglobin to oxygen but increases its affinity to hydrogenCorrect
(D)decreases the affinity of haemoglobin to both oxygen and hydrogen

Answer: (C)

Solution

By the Bohr effect, a high concentration of CO (and the accompanying fall in pH) decreases haemoglobin's affinity for oxygen, promoting O release to the
