What type of protein is fibrin?
Correct answer: A. Fibrous
- A. Fibrous
- B. Structural
- C. Enzymatic
- D. All of the Above
Explanation
Fibrin is a fibrous protein and specifically, it is the main component of blood clots. Fibrin is formed through the enzymatic cleavage of fibrinogen, a soluble plasma protein, during the process of blood clotting. This conversion is catalyzed by the enzyme thrombin. Fibrin molecules then polymerize to form a mesh-like structure, which provides a framework for blood clot formation and stabilization. This network of fibrin strands helps to trap blood cells, platelets, and other components, leading to the formation of a stable blood clot.

About Proteins
Proteins are polymers of amino acids joined by peptide bonds, and their function depends on primary, secondary, tertiary and quaternary structure. The topic covers fibrous and globular proteins, enzymes, antibodies, hormones and transport proteins, as well as denaturation by heat or extreme pH.
