1 About 20-25 per cent of carbon dioxide is transported from the tissues to the lungs as carbaminohaemoglobin.
2 Binding of carbon dioxide to haemoglobin is related to \(\mathrm{pCO}_{2}\)
3 Binding of carbon dioxide to haemoglobin is not affected by \(\mathrm{pO}_{2}\)
4 Carbamino-haemoglobin dissociates into \(\mathrm{CO}_{2}\) and haemoglobin at the alveoli.
Explanation:
The binding of \(\mathrm{CO}_{2}\) to haemoglobin is related to the partial pressure of \(\mathrm{CO}_{2} \cdot \mathrm{pO}_{2}\) is a major factor which could affect this binding.

When percentage saturation of haemoglobin with oxygen is plotted against the \(\mathrm{pO}_{2}\), The curve is called oxygen dissociation curve. The shape of curve is -
1 Rectangular hyperbola
2 Sigmoid
3 Straight line
4 None of the above
Explanation:
When percentage saturation of haemoglobin with oxygen is plotted against the \(\mathrm{pO}_{2}\). This curve is called oxygen dissociation curve. The shape of curve is sigmoid.

Assertion : Haemoglobin cannot get saturated with oxygen more than \(97 \%\) Reason : With a rise in \(\mathrm{PO}_{2}\), the affinity between \(\mathrm{O}_{2}\) and haemoglobin also increases.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
