What is the function of gastric juice What is it made of?

Gastric acid, gastric juice, or stomach acid, is a digestive fluid formed within the stomach lining. With a pH between 1 and 3, gastric acid plays a key role in digestion of proteins by activating digestive enzymes, which together break down the long chains of amino acids of proteins.

What are the functions of gastric juices Class 10?

The HCL present in the gastric juice dissolves bits of food and creates an acidic medium in our stomach. The enzyme pepsinogen is converted to pepsin in this acidic medium. Pepsinogen is a protein-digesting enzyme. It also kills bacteria and other microorganisms that enter along with the food in our stomach.

What are the functions of HCL in our stomach?

Hydrochloric acid is an essential acid in the stomach. It helps destroy bacteria, as well as other harmful species. It also works as a preservative of food. HCl converts pepsinogen which is not active into pepsin to metabolize proteins in our stomach.

What are the 3 main hormones that regulate digestion?

Gastric secretion is stimulated chiefly by three chemicals: acetylcholine (ACh), histamine, and gastrin. Below pH of 2, stomach acid inhibits the parietal cells and G cells; this is a negative feedback loop that winds down the gastric phase as the need for pepsin and HCl declines.

What is a major function of pancreatic juice?

What are the 4 main functions of water in the body?
