Vedclass · Answer

(A) Assertion $(A)$ is true because enzymes are biocatalysts,which are typically large,complex protein molecules with high molecular weights.Reason $(R)$ is also true because almost all enzymes are proteins (with the exception of ribozymes). As proteins,they exhibit all characteristic properties of proteins,such as specific three-dimensional folding,sensitivity to temperature and pH,and the presence of peptide bonds.Since enzymes are proteins,their high molecular weight and complex structure are direct consequences of their proteinaceous nature. Therefore,$R$ is the correct explanation of $A$.

$A$: Enzymes have high molecular weight and complex structures.
$R$: Every enzyme possesses all the properties associated with proteins.
