The protein precursor to fibrin is?

Explanation:
During blood clotting, a soluble plasma protein called fibrinogen is converted into the insoluble protein fibrin, which forms the mesh of the clot. This transformation is driven by the enzyme thrombin, which cleaves fibrinogen to release fibrinopeptides and allow fibrin monomers to polymerize into a stabilizing fibrin network; Factor XIII then cross-links the strands to strengthen the clot. Fibrinogen is produced by the liver and circulates in blood, serving as the precursor to fibrin. Fibrin is the product, not the precursor, and collagen and elastin are structural proteins in connective tissue, not involved in forming fibrin from its precursor.
