_________ stimulates the production of gastric juice in the stomach:
Correct answer: A. Gastrin
- A. Gastrin
- B. Enterokinase
- C. Rennin
- D. None of these
Explanation
Gastrin is a hormone released mainly by the stomach lining that stimulates secretion of gastric juice, including hydrochloric acid and digestive enzymes. Students may choose rennin because it is also a stomach enzyme, but rennin digests milk protein and does not stimulate gastric secretion.
