Coagulation Factor Role A. Fibrinogen 1. Forms a mesh to stabilize the clot B. Thrombin 2. Converts into thrombin C. Prothrombin 3. Converts fibrinogen to fibrin D. Calcium ions 4. Required for several clotting steps

Step-by-step solution

Fibrinogen is a soluble protein that, when activated, forms fibrin, which creates a mesh-like structure to stabilize the blood clot. Thrombin is an enzyme that plays a crucial role in blood clotting by converting fibrinogen to fibrin. Prothrombin is an inactive precursor of thrombin. During the clotting process, it is converted into thrombin, which then catalyzes the conversion of fibrinogen to fibrin. Calcium ions are essential for several steps in the blood coagulation process.
