Question

classify the listed substances as either carbohydrates, lipids, proteins, or nucleic acids: enzymes actin polypeptide rna antibodies nucleotides dna myosin hormones

Explanation:

Enzymes are proteins that catalyze biochemical reactions. Actin is a protein involved in muscle - contraction and cell movement. Polypeptides are chains of amino - acids and are proteins. Antibodies are proteins that help in the immune response. Myosin is a protein involved in muscle contraction. Hormones can be proteins (e.g., insulin), but some are lipids or other types. RNA and DNA are nucleic acids, and nucleotides are the building blocks of nucleic acids. Since no lipids are listed among the given substances, the lipid box will be empty.

Answer:

Carbohydrate: (empty)
Lipid: (empty)
Protein: Enzymes, Actin, Polypeptide, Antibodies, Myosin
Nucleic Acid: RNA, Nucleotides, DNA
Hormones: Can be protein or other types (incomplete classification without more information)
