Mechanism of blood clotting is given below:
An injury or a trauma stimulates the platelets in the blood to release certain factors which activate the mechanism of coagulation. An enzyme complex, ______P_______ is formed by a series of linked enzymic reactions (______Q_______process) involving a number of factors present in the plasma in an inactive state. This enzyme complex is required for formation of______R_______. _____S_______ ions play a very important role in clotting.
