Question

What is the primary function of the protein collagen in the human body?

• A. Structural support in connective tissues
• B. Enzyme catalysis
• C. Transport of oxygen in the blood
• D. Muscle contraction

Hint:

Collagen is crucial for maintaining the integrity and strength of connective tissues throughout the body, making it essential for skin elasticity and joint health.

Answer 1

The Correct Option is A

Collagen is the most abundant protein in the human body and plays a vital role in providing structural support to connective tissues such as skin, tendons, ligaments, and bones. It helps maintain the shape and integrity of various tissues and organs, offering mechanical strength and flexibility.

(1) Structural Support in Connective Tissues:
- Collagen fibers provide tensile strength and elasticity to tissues. The protein is a key component of extracellular matrices and plays a crucial role in tissue repair and regeneration.

(2) Why Other Options Are Incorrect:
- Enzyme catalysis (Option 2) refers to the function of enzymes, not structural proteins like collagen.
- Transport of oxygen in the blood (Option 3) is the primary function of hemoglobin, not collagen.
- Muscle contraction (Option 4) is facilitated by proteins like actin and myosin, not collagen.

Conclusion: The primary function of collagen in the human body is to provide structural support in connective tissues.
