Vedclass · Answer

(A) Metabolism is the sum total of all chemical reactions occurring in a living organism. Statement $X$ is correct because metabolism is a defining feature of all living organisms,and non-living objects do not show metabolic activities. Statement $Y$ is also correct because metabolic reactions can be performed in vitro (outside the body in a cell-free system). Such reactions are considered living reactions,although the system itself is not a living organism. Therefore,both statements are correct.

$X$ - No non-living objects exhibit metabolism.
$Y$ - Metabolic reactions can be demonstrated outside the body in a cell-free system.
