Which type of cell in the stomach is responsible for producing the digestive enzyme pepsinogen?
A
Enteroendocrine cells
B
Chief cells
C
Goblet cells
D
Parietal cells
Verified step by step guidance1
Understand the function of each cell type listed in the options: Chief cells, Enteroendocrine cells, Goblet cells, and Parietal cells.
Recall that pepsinogen is an inactive precursor to the enzyme pepsin, which is involved in protein digestion in the stomach.
Learn that Chief cells are specialized cells in the stomach lining responsible for secreting pepsinogen.
Note that Enteroendocrine cells produce hormones like gastrin, Goblet cells secrete mucus to protect the stomach lining, and Parietal cells produce hydrochloric acid (HCl).
Conclude that Chief cells are the correct answer because they are directly responsible for producing pepsinogen, which is activated into pepsin in the presence of HCl.
