Examples [edit]. Examples of zymogens include: Pepsinogen, inactive precursor form of pepsin, is secreted by Chief cells in the stomach. Pepsinogen is activated by Hydrochloric acid (secretion from Parietal cells) because Hydrochloric acid provides the necessary acidic environment for which pepsin works best.xamples [edit].
