Verified step by step guidance1
Understand that enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.
Recall the four major classes of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
Recognize that enzymes are primarily composed of amino acids linked together in specific sequences, which fold into unique three-dimensional structures necessary for their catalytic activity.
Identify that proteins are the class of macromolecules made up of amino acids and are responsible for most enzymatic functions in cells.
Conclude that since enzymes are mostly proteins, the correct class of biological macromolecule for most enzymes is protein.
