Assertion : Trypsin helps in blood digestion of predator aimals.
Reason : Trypsin hydrolyses fibrinogen.
Trypsin is protein digesting enzyme present in the intestine of animals. Though it cannot digest casein (a milk protein), in predator animals drinking the blood of their prey, trypsin hydrolyses fibriongen of blood into fibrin, leading to blood coagulation thus help in blood digestion. It also activates other pancreatic proteases.
