In the digestive system, some protease enzymes must be secreted as an inactive form and then activated later by proteolytic cleavage once outside of the secreting cell to prevent active proteases from damaging the secreting cells.What is the category of precursor proteins of this type?
A)ubiquitins
B)zymogens
C)glycosides
D)activins
