Which of the following is not a fibrous protein?
Correct answer: D. Hormones
- A. Keratin
- B. Myosin
- C. Fibrin
- D. Hormones
Explanation
The correct answer is hormones. Hormones are biochemical messengers that are typically not proteins, and when they are, they are not fibrous. They serve regulatory functions rather than structural roles. Keratin is a classic example of a fibrous protein, providing structural support in hair and nails. Myosin, although having a fibrous appearance, is primarily a motor protein involved in muscle contraction. Fibrin is a fibrous protein that helps in blood clotting by forming a mesh structure. Therefore, hormones do not fit in the category of fibrous proteins.

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.
