What catalyzes the conversion of fibrinogen to fibrin?

Question

Quizplus · Accepted Answer

Thrombin catalyzes the conversion of fibrinogen to fibrin by cleaving fibrinogen at specific sites, resulting in the formation of monomers that polymerize to form fibrin threads. Calcium and coagulation factors are necessary for the activation of thrombin in the coagulation cascade, but they do not directly convert fibrinogen to fibrin. Prothrombin is not directly involved in the conversion of fibrinogen to fibrin.
