EVERYDAY SCIENCE

Detailed explanation-1: -Detailed evidence has been accumulating that at least one chain reaction occurs during the coagulation of blood. Both the metamorphosis of platelets and the development of thrombokinase appear to be involved. The autocatalytic effect may serve a function in making possible the growth of a hemostatic plug.

Detailed explanation-2: -When a wound damages the wall of a blood vessel wall, it sets off a complex set of chemical reactions involving these coagulation factors. The process is like a cascade of chemical reactions, as it happens step by step.

Detailed explanation-3: -The plasma clotting cascade consists of a series of reactions involving the activation of zymogens (inert precursors of enzymes) via limited proteolysis. The resulting enzymes are catalytically active serine proteases, yet they have low inherent enzymatic activity as isolated proteins.

Detailed explanation-4: -Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.
