Keratin and collagen are examples of which type of protein?

• A. Enzymatic
• B. Structural
• C. Transport
• D. Contractile

Answer: (B)

Keratin and collagen are classified as structural proteins due to their primary role in providing support and strength to various tissues in the body. Structural proteins are essential components in the formation of cellular structures, contributing to the integrity and resilience of tissues such as skin, bones, tendons, and cartilage. Keratin, found in hair, nails, and the outer layer of skin, serves as a protective barrier, enhancing durability against environmental damage. Collagen, on the other hand, is the most abundant protein in the body, primarily found in connective tissues, and is crucial for maintaining tissue structure and elasticity. Their roles as foundational components highlight the significance of structural proteins in maintaining the overall architecture and functionality of biological systems.
