Prothrombin Thrombin In this way, the

thrombin.
Thrombin
Fibrinogen Fibrin
Thrombin converts fib-
rinogen into fibers of
fibrin, enabling the clot
to form.
The enzymes that enable blood clotting literally know what needs to happen when,
where they must concentrate, which gap in the body they need to close, and what se-
quence they need to follow. This immaculate system is too complex for any of its
stages to have come about by chance.
the fibrin clots. Plasmin works on fibrin, but not on fibrinogen, the lat-
ter's inactive state. Were that not so, it would cause a serious difficulty
for future clotting. Plasmin cannot act too quickly, which is actually an
advantage: Otherwise, the wound would not heal before plasmin,
which is activated when the wound appears, had severed the fibrin,
breaking down clots as soon as they formed.
There are numerous other enzymes involved in the blood clotting
system. Each is necessary to carry out or complete a particular process,
and all are parts of an irreducibly complex system from which not a sin-
gle component can be removed.
