Verified step by step guidance

Step 1: Begin by understanding the role of enzymes in biochemical processes. Enzymes are biological catalysts that speed up chemical reactions without being consumed in the process.

Step 2: Recall the major classes of biomolecules: carbohydrates, nucleic acids, lipids, and proteins. Each class has distinct functions and structures.

Step 3: Analyze the structural composition of enzymes. Enzymes are primarily composed of amino acids, which are the building blocks of proteins. This makes enzymes a type of protein.

Step 4: Consider the functional properties of proteins. Proteins are versatile molecules that can fold into specific shapes, enabling them to act as enzymes and bind to substrates with high specificity.

Step 5: Conclude that enzymes are proteins based on their structure and function, distinguishing them from carbohydrates, nucleic acids, and lipids, which serve different roles in the cell.
