Vedclass · Accepted Answer

Heparin

Vedclass · Answer

(A) Blood clotting (coagulation) is a complex process involving various clotting factors. $1$. Heparin is a natural anticoagulant present in the blood that prevents clotting within the blood vessels. Therefore,it does not help in the process of blood clotting; rather,it inhibits it. $2$. Prothrombin is a precursor protein that is converted into thrombin,which is essential for the formation of a fibrin mesh. $3$. $Ca^{2+}$ ions are crucial cofactors for several steps in the coagulation cascade. $4$. Exposure to $O_2$ (air) is a physical factor that triggers the clotting process when blood leaves the vessels. Thus,Heparin is the correct answer.
