So if we don't have vitamin K, if we have a vitamin K deficiency in our body, that will basically mean that protein C cannot actually function properly. Now, protease basically means when it acts with its target molecule, it hydrolyzes, it breaks the peptide bonds at specific sites on the target molecule. So protein C is a protease, meaning it digests its target molecule. So protein C, interestingly, is actually activated by thrombin. And thrombin is that very same molecule that is used to actually form fibrin from fibrinogen. And fibrin is used to form the blood clots.
