Vedclass · Answer

(B) $1$. Disaccharides (like sucrose,lactose,and maltose) are sugars,and by definition,they are sweet in taste. Thus,statement $S$ is true.$2$. Disaccharides are large,polar,water-soluble molecules. Due to their size and polarity,they cannot pass through the lipid bilayer of the cell membrane by simple diffusion. They require specific transport proteins to enter the cell. Thus,statement $R$ is true.$3$. However,the reason why they cannot pass through the cell membrane (their size and polarity) is not the reason why they are sweet. Therefore,$R$ is not the correct explanation of $S$.

$S$ - Statement: Disaccharides are sweet in taste.
$R$ - Reason: They cannot pass through the cell membrane.
