Question

Quizplus · Accepted Answer

Thrombin is the blood enzyme that converts fibrinogen into fibrin, which then forms a clot. Thromboplastin is a coagulation factor that initiates the clotting cascade, but it does not directly form fibrin. Globulin refers to a group of proteins in the blood, and heparin is an anticoagulant that inhibits clotting.
