NEET · Biology · STD 11 - 14. Breathing and exchange in gases
Reduction in \(pH\) of blood will
- A decrease the affinity of haemoglobin with oxygen
- B release bicarbonate ions by the liver
- C reduce the rate of heart beat
- D reduce the blood supply to the brain.
Answer & Solution
Correct Answer
(A) decrease the affinity of haemoglobin with oxygen
Step-by-step Solution
Detailed explanation
(a) : Reduction in \(pH\) of blood causes oxygen haemoglobin dissociation curve to shift to right which indicates dissociation of oxygen from haemoglobin. This decreases affinity of haemoglobin for oxygen.
