In what form does thrombin normally exist in the plasma?​

Quizplus · Accepted Answer

Thrombin is formed from prothrombin through the action of various clotting factors. Therefore, thrombin does not normally exist in the plasma, but rather in the form of prothrombin. Fibrinogen is also present in the plasma and is converted into fibrin by thrombin during the clotting process. Protothrombin and prethrombin are not typically found in the plasma. Thrombin stabilizing factor is not a form of thrombin but rather a protein that helps to stabilize thrombin in the clotting process.
