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.This is 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

Question

Quizplus · Accepted Answer

Zymogens are precursor proteins that are secreted in an inactive form and are activated later by proteolytic cleavage outside of the secreting cell. This activation prevents the active proteases from damaging the secreting cells. Ubiquitins are small regulatory proteins that play a role in protein degradation, glycosides are a category of organic compounds commonly found in plants, and Activins are polypeptide hormones with many biological functions.
