Verified step by step guidance

Understand the definition of enzymes: Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.

Recall the major types of macromolecules: Proteins, lipids, nucleic acids, and carbohydrates are the four main categories of macromolecules found in biological systems.

Identify the structural composition of enzymes: Enzymes are primarily composed of amino acids, which are the building blocks of proteins. This means enzymes are proteins.

Differentiate enzymes from other macromolecules: Lipids, nucleic acids, and carbohydrates do not have the structural or functional properties required to act as enzymes. Proteins, due to their ability to fold into specific three-dimensional shapes, are uniquely suited to perform enzymatic functions.

Conclude that enzymes are classified as proteins based on their structure and function, and eliminate the other options (lipids, nucleic acids, carbohydrates) as incorrect.
