Detailed explanation-1: -Thrombin is a naturally occurring enzyme, which is responsible for blood clotting.
Detailed explanation-2: -Blood-clotting proteins generate thrombin, an enzyme that converts fibrinogen to fibrin, and a reaction that leads to the formation of a fibrin clot.
Detailed explanation-3: -Thrombokinase is an enzyme present in platelets of blood. Thrombokinase is required in blood clotting.
Detailed explanation-4: -Like trypsin, thrombokinase can activate prothrombin without the aid of other factors; however, it is potentiated by platelets plus calcium. Unlike certain tissue “thromboplastins, ” it does not sediment appreciably in 2 hours at 85, 000 g. Like trypsin, it hydrolyzes p-toluenesulfonylarginine methyl ester (TAMe).
Detailed explanation-5: -Tissue factor (also known as tissue thromboplastin or CD142) is the protein that activates the blood clotting system by binding to, and activating, the plasma serine protease, factor VIIa, following vascular injury.
