Structural proteins are usually:
Correct answer: B. Fibrous
- A. Enzymatic
- B. Fibrous
- C. Soluble
- D. Globular
Explanation
Fibrous proteins are a class of proteins characterized by their elongated, thread-like structures. These proteins are often insoluble in water and play key roles in providing structural support and strength to cells and tissues. The structure of fibrous proteins is well-suited for their functions, and they are distinct from globular proteins, which have more compact, spherical shapes.

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.
