Current Question (ID: 14190)

Question:

The parietal cells or the oxyntic cells located in the stomach's gastric pits mainly secrete:-

Options:

1. HCl and Intrinsic factor
2. Pepsinogen and Gastric lipase
3. Pepsinogen and Pro-rennin
4. Gastrin and Mucus

Solution:

HCl is responsible for creating an acidic environment in the stomach, which is necessary for the activation of the enzyme pepsinogen to its active form, pepsin. Pepsin helps to break down proteins into smaller peptides and amino acids. Intrinsic factor is necessary for the absorption of vitamin B12 in the small intestine. Gastric lipase is secreted by chief cells, which are also located in the gastric pits of the stomach, and it helps to break down fats. Pepsinogen is also secreted by chief cells and is converted to pepsin by HCl. Pro-rennin is not a digestive enzyme produced by the stomach. Gastrin is a hormone produced by G cells in the stomach and stimulates acid secretion, while mucus is secreted by goblet cells in the stomach to protect the stomach lining from the acidic environment.
