Enzymes, antibodies. hormones and hemoglobin are examples of:
Correct answer: B. Globular proteins
- A. Fibril proteins
- B. Globular proteins
- C. Fibrous proteins
- D. Tough proteins
Explanation
Globular proteins are characterized by their spherical shape due to their tertiary and quaternary structures. This shape is crucial for their roles in biological processes. Enzymes, antibodies, hormones, and hemoglobin all fall under this category because their functions rely on complex folding patterns that allow for interaction with other molecules. In contrast, fibril and fibrous proteins are more structural, lacking the complexity needed for the dynamic roles of globular proteins. Tough proteins like keratin serve protective roles rather than biochemical functions.

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.
