These are polymers of amino acids:
Correct answer: D. Proteins
- A. Hormones
- B. Enzymes
- C. Hemoglobin
- D. Proteins
Explanation
Proteins are polymers of amino acids linked together by peptide bonds. They are essential biological molecules with diverse functions, such as enzymes catalyzing reactions, structural components providing support, hormones regulating processes, and transporters moving substances across membranes. Other options like hormones, enzymes, or hemoglobin are specific types of proteins or molecules that do not encompass the full scope of what proteins are.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
