NEET · Biology · STD 11 - 14. Breathing and exchange in gases
Match the following columns and select the correct option
| Column \(I\) | Column \(II\) |
| (\(a\)) Pneumotaxic Centre | (\(i\)) Alveoli |
| (\(b\)) \(O _{2}\) Dissociation curve | (\(ii\)) Pons region of brain |
| (\(c\)) Carbonic Anhydrase | (\(iii\) Haemoglobin |
| (\(d\)) Primary site of exchange of gases | (\(iv\)) \(R.B.C.\) |
- A \((a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)\)
- B \((a)-(i), (b)-(iii), (c)-(ii), (d)-(iv)\)
- C \((a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)\)
- D \((a)-(iii), (b)-(ii), (c)-(iv), (d)-(i)\)
Answer & Solution
Correct Answer
(C) \((a)-(ii), (b)-(iii), (c)-(iv), (d)-(i)\)
Step-by-step Solution
Detailed explanation
The correct answer is option (3) because pneumotaxic centre is present in the pons region of the brain. In \(O _{2}\) dissociation curve, percentage saturation of haemoglobin is plotted against the \(pO _{2}\). Carbonic anhydrase is mainly present in the RBCs and its minute quantity is present in the plasma.
