Explanation:
Detailed explanation-1: -Prothrombin is present in the bloodstream in its inactive form. It is released by blood platelets and converted to its active form, thrombin, in response to an injury by an enzyme complex, thrombokinase.
Detailed explanation-2: -Thrombocytes, also called as platelets, release the chemical called thromboplastin at the site of injury. The thromboplastin further converts inactive prothrombin into Thrombin. Thrombin, in turn, converts inactive fibrinogen into fibrin.
