Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells.

True

False

The statement given in the question is FALSE.

Explanation:

Pepsinogen is a zymogen, an inactive form of pepsin. Pepsinogen is secreted by the mucous cells and the gastric chief cells, which are located in the stomach into the gastric juice. Pepsinogen becomes an active enzyme (pepsin) when it comes in contact with the hydrochloric acid in the stomach. The hydrochloric acid is secreted by the gastric parietal cells. The active enzyme pepsin is responsible for the breaking down of proteins molecules during digestion.
