E) albumin, … WebPlasmin is a serine protease that acts to dissolve fibrin blood clots. Apart from fibrinolysis, plasmin proteolyses proteins in various other systems: It activates collagenases, some mediators of the complement system, and weakens the wall of the Graafian follicle, leading to ovulation. Plasmin is also integrally involved in inflammation. [6]
WebAt the end of the cascade, fibrinogen is converted to fibrin. Fibrin is an insoluble protein that forms a threaded mesh over the injury site. Thrombin is the enzyme that activates this conversion.
