Which macromolecule group includes enzymes?

Which macromolecule group includes enzymes?

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

Answer: (A)

Enzymes are primarily proteins that act as biological catalysts, made from amino acids folded into specific shapes with active sites that bind substrates. This structure lets them lower the activation energy of chemical reactions, speeding them up to fit cellular needs. While there are rare RNA-based catalysts called ribozymes, the vast majority of enzymes belong to the protein macromolecule group, not carbohydrates, lipids, or nucleic acids. Carbohydrates and lipids have roles in energy storage and membranes, and nucleic acids store and transmit genetic information (with some catalytic roles in a few RNA enzymes), but when you hear “enzymes,” think proteins because of their versatile and highly specific catalytic capabilities.
