Verified step by step guidance

Understand the categories of organic molecules: Organic molecules are broadly classified into lipids, carbohydrates, nucleic acids, and proteins. Each category has distinct structural and functional characteristics.

Recall the structure and function of actin: Actin is a globular protein that plays a critical role in cell structure and motility, forming part of the cytoskeleton.

Identify the category of actin: Proteins are composed of amino acids linked by peptide bonds, and actin is made up of amino acid chains, fitting the definition of a protein.

Eliminate incorrect options: Lipids are primarily involved in energy storage and membrane structure, carbohydrates are sugars and polysaccharides, and nucleic acids (DNA and RNA) store genetic information. Actin does not fit into these categories.

Conclude that actin belongs to the protein category based on its structure and function as a polymer of amino acids.
