Explanation:

The primary structure of an enzyme is the linear sequence of amino - acids. This sequence determines the way the enzyme folds into its overall three - dimensional shape. Different amino - acids have different chemical properties. For example, hydrophobic amino - acids tend to cluster in the interior of the folded enzyme to avoid water, while hydrophilic amino - acids are on the surface. The specific order of amino - acids in the primary structure dictates the pattern of hydrogen bonding, disulfide bond formation (if applicable), and other interactions that lead to the unique overall shape of the enzyme. This shape is crucial for the enzyme's function as it determines the active site where the substrate binds and the reaction occurs.

Answer:

The primary structure of an enzyme, which is the linear sequence of amino - acids, determines its overall shape. The chemical properties of individual amino - acids in the sequence drive the folding process through interactions such as hydrogen bonding, disulfide bond formation, and hydrophobic/hydrophilic interactions. This results in a unique three - dimensional shape that is essential for the enzyme's function, including the formation of the active site for substrate binding and catalysis.
