Which protein has a fibrous structure?
Correct answer: E. C and D
- A. Amylase
- B. Haemoglobin
- C. Collagen
- D. Keratin
- E. C and D
Explanation
The correct answer is Option E: C and D, as both Collagen and Keratin are fibrous proteins. Collagen is crucial for the structural integrity of connective tissues, providing strength and support. Keratin, on the other hand, is essential for the protection and durability of skin, hair, and nails. These proteins have fibrous structures that are fundamentally different from the globular structures seen in proteins like Amylase and Haemoglobin. Amylase, a globular enzyme, functions in starch digestion, while Haemoglobin, another globular protein, efficiently carries oxygen in the blood.

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.
