Thromboplastin

Vedclass · Answer

(D) Blood clotting (coagulation) is a complex process involving a cascade of clotting factors. $Thromboplastin$ is a lipoprotein released by injured tissues or platelets that initiates the extrinsic pathway of blood coagulation. When $Thromboplastin$ is introduced into the bloodstream,it acts as a catalyst for the conversion of prothrombin to thrombin,which subsequently converts fibrinogen into fibrin,leading to the formation of a blood clot at the site of introduction. $Fibrinogen$ and $Prothrombin$ are inactive precursors already present in the blood,while $Heparin$ is an anticoagulant that prevents clotting.

Which of the following substances,if introduced into the bloodstream,would cause blood clotting at the site of introduction?
