Enzymes are primarily composed of proteins. These large biomolecules are essential for facilitating biochemical reactions in living organisms by acting as catalysts. Each enzyme is composed of long chains of amino acids, which fold into specific three-dimensional shapes. This structure is critical as it determines the enzyme's activity and specificity, enabling it to bind to its substrate and catalyze a reaction effectively.

While other biomolecules, such as carbohydrates, lipids, and nucleic acids, play significant roles in cellular functions, they do not serve as the primary components of enzymes. Carbohydrates mainly provide energy and serve structural roles, lipids are crucial for membrane structure and energy storage, and nucleic acids are involved in the storage and expression of genetic information. Therefore, the uniqueness of enzymes as proteins highlights their crucial function in biological processes, making this answer the most accurate choice.
