Question

What occurs during the blood clotting process? A. Prothrombin is converted into thrombin which acts on fibrinogen. B. Prothrombin is converted into thrombin which acts on fibrin. C. Fibrinogen is converted into fibrin which acts on prothrombin. D. Fibrinogen is converted into fibrin which acts on thrombin.

Answer 1

Answer: A. Prothrombin is converted into thrombin which acts on fibrinogen.

Explanation:

Prothrombin is a protein which is converted into thrombin through a blood clotting factor that is known as factor X or prothrombinase.

Thrombin then transform the fibrinogen protein into fibrin threads. The fibrin thread acts like a wire mesh to trap the blood cells and forms a scab or clot. This entire process is called as coagulation.
