What type of macromolecule are enzymes?

• A. Lipids
• B. Carbohydrates
• C. Proteins
• D. Nucleic acids

Answer: (C)

Enzymes are classified as proteins, which are one of the four main types of macromolecules necessary for life. They are made up of long chains of amino acids that fold into specific three-dimensional structures, allowing them to catalyze biochemical reactions by lowering the activation energy required for the reactions to occur. This catalytic efficiency is crucial for sustaining life processes, as enzymes enable reactions to happen quickly and at temperatures suitable for biological systems. The specific structure of proteins allows enzymes to have active sites that interact selectively with substrates, making them highly specific in their function. Enzymes also undergo changes in shape during the reaction process, a feature that helps in the binding and release of substrates and products. Other types of macromolecules serve different functions; for instance, lipids primarily serve as structural components and long-term energy storage, carbohydrates function in energy provision and structural roles, and nucleic acids are involved in the storage and expression of genetic information. However, the distinctive role of enzymes as catalysts firmly establishes them within the category of proteins.
