Assertion: Oxyhaemoglobin dissociates near the organ tissue due to Bohr effect and oxygen is released.
Reason: Increased CO2 concentration reduces the affinity of haemoglobin for oxygen.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
(b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
(c) If Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Explanation:
Bohr's effect is the effect of CO2 on oxyhaemoglobin. Body tissues obtain oxygen from oxyhaemoglobin because of its dissociation caused by low O2 and high CO2 concentration. The increased CO2 concentration reduces the affinity of haemoglobin for oxygen.
