Vedclass · Answer

(B) The given graph represents the oxygen-haemoglobin dissociation curve.In the lungs,the partial pressure of $O_{2}$ $(pO_{2})$ is high,which facilitates the binding of $O_{2}$ with haemoglobin,leading to high percentage saturation of haemoglobin. This corresponds to point $A$ on the curve.In the tissues,the partial pressure of $O_{2}$ $(pO_{2})$ is low due to metabolic activity,which causes the dissociation of $O_{2}$ from oxyhaemoglobin,leading to lower percentage saturation. This corresponds to point $B$ on the curve.Therefore,$A$ represents lungs and $B$ represents tissues.

Identify $A$ and $B$ in the given oxygen-haemoglobin dissociation curve and choose the correct option accordingly.

What are the major transport mechanisms for $CO_{2}$? Explain.

During oxygen transport,the oxyhaemoglobin at the tissue level liberates oxygen to the cells because

$I.$ Increased partial pressure of $O_{2}$
$II.$ Increased partial pressure of $CO_{2}$
$III.$ Increased partial pressure of $H^{+}$
$IV.$ Decreased partial pressure of $O_{2}$
All the above situations favour the dissociation of oxyhaemoglobin except:
