Which secretory cell of the stomach, shown in the following image, secretes pepsinogen?
Parietal cell
Mucous neck cell
Chief cell
Enteroendocrine cell
The Correct Answer is C
A. Parietal Cell: Parietal cells are responsible for secreting hydrochloric acid (HCl) and intrinsic factor, not pepsinogen. HCl activates pepsinogen into pepsin.
B. Mucous Neck Cell: Mucous neck cells secrete mucus to protect the gastric lining but do not secrete pepsinogen.
C. Chief Cell: Chief cells (also known as zymogenic cells) are specialized cells in the stomach that secrete pepsinogen, the inactive precursor of the digestive enzyme pepsin.
D. Enteroendocrine Cell: Enteroendocrine cells secrete hormones like gastrin, which regulates digestive processes, but they do not secrete pepsinogen.
