Final answer:
Prothrombin is a plasma protein which gets converted to thrombin during blood coagulation. This process is aided by Prothrombin activator. Tissue factor and PF3 are also involved in this process.
Step-by-step explanation:
The term 'tissue factor PF3 Prothrombin activator' appears to involve the process of blood clotting or coagulation, which is a key event in human biology. Prothrombin is a protein produced by the liver, present in blood plasma which gets converted into thrombin during the process of coagulation. This conversion is enabled by Prothrombin activator. Tissue factor, in conjunction with factor VII, is involved in initiating the cascade of reactions during blood coagulation. PF3, or Platelet Factor 3, is a phospholipid available on the surface of platelets, enhancing the formation of Prothrombin activator complex.
