Question

What is the role of Pepsin and Hydrochloric acid in our bodies?

Answer 1

Hcl provides acidic median to food for the work to pepsin
hcl kills germs and bacteria present along with food
pepsin breaks protien into dipeptide peptone

Answer 2

Pepsin is an enzyme that breaks down proteins into smaller peptides (that is, a protease). It is produced in the stomach and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

HCl also has another important role to play in the stomach during the digestion process. The presence of HCl in the body of the stomach causes the activation of enzymes. One of the proteins in HCl is used to convert the enzyme pepsinogen intopepsin.
