Question

Which of these help in blood clotting?

• A. Sodium.
• B. Bilirubin.
• C. Fibrinogen.
• D. None of the above.

Answer 1

The correct option is C Fibrinogen.

The mechanism of blood clotting involves The presence of calcium and other clotting factors, Factor X activates an enzyme called prothrombin activator. The enzyme prothrombin activator then converts plasma protein prothrombin into thrombin. Thrombin is the enzyme which in turn converts fibrinogen into fibrin. Polymerized fibrin together with platelets forms a clot at the wound site. Fibrinogen is a blood plasma protein made in liver and present in circulating blood. Hence fibrinogen helps in blood clotting by converting into fibrin which in turn forms a blood clot and stops bleeding.

So, the correct answer is 'Fibrinogen'.
