Understand that enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process.
Recall the four major types of biological macromolecules: proteins, nucleic acids, carbohydrates, and lipids.
Recognize that enzymes are primarily composed of amino acids linked together in specific sequences, forming proteins.
Note that while nucleic acids (DNA and RNA) store genetic information, carbohydrates provide energy, and lipids serve as energy storage and structural components, enzymes function as proteins.
Conclude that enzymes are classified as proteins because their structure and function depend on the specific sequence and folding of amino acids.
