The suffix "-globin" denotes which type of molecule?

• A. Sugar
• B. Blood
• C. Protein
• D. Gums

Answer: (C)

The suffix -globin identifies a protein. Globin proteins are a family that includes hemoglobin and myoglobin—proteins that bind heme and are involved in oxygen transport and storage. It’s not used for sugars, gums, or the blood itself; it names the protein component. So the best answer is protein.
