Vedclass · Answer

(A) The diffusion rate of a gas across the alveolar membrane is directly proportional to its solubility and the partial pressure gradient.Carbon dioxide $(CO_2)$ is $20-25$ times more soluble than oxygen $(O_2)$ in the blood and alveolar membranes.Due to this significantly higher solubility,the diffusion rate of $CO_2$ is much faster than that of $O_2$ for the same partial pressure gradient.Therefore,both the assertion and the reason are correct,and the reason provides the correct explanation for the assertion.

$A$: Diffusion of carbon dioxide is $20$ times faster than oxygen.
$R$: It is due to difference in partial pressure as well as solubility of diffusing gases.
