Multiple choice

Collagen fibers are stronger than steel fibers of similar diameter. Why?

  1. They are composed of cross-linked fibrils

  2. They are composed of protein rather than Iron.

  3. They are more stable at body temperature

  4. They are composed of Collagen fibers associated with lipids.

A Correct answer
Explanation

The high tensile strength of collagen fibers is due to their hierarchical structure, where individual collagen molecules form triple helices that pack together and are stabilized by covalent cross-links between adjacent fibrils. Being composed of protein rather than iron does not inherently make something stronger than steel, and lipids do not contribute to this structural strength.
