Question

role of acid in our stomach​

Answer 1

Answer:

Explanation:

Acid in our stomach plays an essential role in the immune system by killing harmful bacteria and parasites that are ingested with food. Stomach acid activates the enzyme pepsin needed for protein digestion. Stomach acid signals to the pancreas produce digestive juices and enzymes to further break down food.

Answer 2

Hydrochloric acid, that is, HCl, is secreted by the gastric glands in our stomach. This acid has two roles:

1) HCl helps to break down the proteins present in the food to make the action of Pepsin (which is an enzyme also secreted by gastric gland) easier.

2) HCl, being a strong acid, helps to kill the harmful bacteria present in the food, thus protecting us from certain harmful diseases.

That's about it. Hope you understand!
