Verified step by step guidance

Step 1: Understand the question by identifying the key term 'enzymes' and its role in biological systems. Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Step 2: Recall the four major categories of organic molecules: carbohydrates, nucleic acids, proteins, and lipids. Each category has distinct functions and structures.

Step 3: Analyze the structural composition of enzymes. Enzymes are made up of amino acids, which are the building blocks of proteins. This indicates that enzymes belong to the protein category.

Step 4: Consider the functional properties of proteins. Proteins are versatile molecules that perform various functions, including acting as enzymes to catalyze biochemical reactions.

Step 5: Confirm the correct answer by matching the structural and functional characteristics of enzymes with the protein category, as enzymes are composed of polypeptide chains folded into specific shapes to perform their catalytic functions.
