Quizplus · Accepted Answer

The two enzymes in the clotting process are prothrombin activator and thrombin. Prothrombin activator is responsible for converting prothrombin (a protein in blood plasma) into thrombin. Thrombin, in turn, converts fibrinogen (another protein in blood plasma) into fibrin, which forms the mesh-like structure of a blood clot.
