Answer
1. Platelets clump at the site of the ruptured blood vessel and attempt to seal the leakage of blood.
2. Platelets release prothrombin activator. This converts prothrombin into thrombin.
3. Thrombin, acting as an enzyme, splits two amino acid chains in a fibrinogen molecule.
4. These parts of amino acid chains string together to form threads of fibrin.
5. Fibrin threads wrap around platelets to better seal the clot preventing more blood loss.
