Verified step by step guidance

Understand the nature of fibrous proteins: Fibrous proteins are typically elongated, insoluble, and have structural roles in cells and tissues. They differ from globular proteins, which are more compact and often involved in dynamic functions like catalysis or transport.

Review the functions of fibrous proteins: Common examples include collagen, keratin, and elastin. These proteins provide mechanical strength, elasticity, and structural integrity to tissues such as skin, tendons, and bones.

Eliminate incorrect options: Serving as antibodies, catalyzing biochemical reactions, and transporting small molecules are functions typically associated with globular proteins, not fibrous proteins.

Focus on the correct function: Fibrous proteins are specialized for providing structural support to cells and tissues, which aligns with their physical properties and roles in the body.

Conclude the reasoning: Based on the characteristics and functions of fibrous proteins, the correct answer is 'Providing structural support to cells and tissues.' This matches their biological role and distinguishes them from globular proteins.
