Question

what biomolecule do enzymes belong to *
protein
carbohydrate
lipid
nucleic acid

Explanation:

Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are made up of amino acids, which are the building blocks of proteins. Proteins are one of the four major biomolecules (along with carbohydrates, lipids, and nucleic acids). The structure and function of enzymes are directly related to their protein nature. For example, the specific shape of an enzyme (determined by its protein structure) allows it to bind to a particular substrate (the molecule upon which the enzyme acts).

Answer:

Protein
