what type of macromolecule is an enzyme?

An enzyme is a type of macromolecule known as a protein. Proteins are made up of long chains of amino acids that fold into unique three-dimensional structures, which enable enzymes to facilitate and accelerate biochemical reactions with high specificity and efficiency. This protein structure includes an active site where substrates bind, lowering the activation energy of reactions, making enzymes essential catalysts in many biological processes such as metabolism, DNA replication, and digestion.
