Final answer:
True, enzymes consist of amino acids with side chains that interact to form the enzyme's tertiary structure, which includes the active site essential for catalytic activity.
Step-by-step explanation:
enzymes are composed of amino acids whose side chains interact with one another to form the enzyme's tertiary structure. These interactions include hydrogen bonds, ionic bonds, hydrophobic interactions, and van der Waals forces.
Enzymes are vital macromolecules, most often proteins, that facilitate chemical reactions within the body by lowering activation energy barriers. They are highly specific for the reactions they catalyze. Enzymes contain an active site, which is crucial for their functional capabilities. The amino acid side chains in or near the active site play a significant role in binding and catalysis. In this region, the side chains can act as acid or base catalysts, help in the transfer of functional groups, or aid in the rearrangement of a substrate. Tertiary structure is key as it brings together amino acids, which are widely separated in the primary sequence, to form a functional active site through the complex three-dimensional folding pattern of the protein. After the enzyme has done its work and the product is released, the active site usually reverts to its original shape, ready to catalyze another reaction.
