What is role of hydrochloric acid in digestion?

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 is the role of hydrochloric acid in protein digestion quizlet?

Which of the following choices describes the role of hydrochloric acid in protein digestion? It activates pepsin and denatures proteins so that pepsin breaks them down. Small protein pieces in the blood might trigger the immune system to react to them which could result in a food allergy or an autoimmune response.

What does HCl with pepsin do?

HCl secretion in the stomach does several positive things. It assists protein digestion by activating pepsinogen to pepsin, it renders the stomach sterile against ingested pathogens, it inhibits undesirable overgrowth in the small intestine, and it encourages the flow of bile and pancreatic enzymes.

What is one purpose of HCl acid in the stomach quizlet?

What is a function of hydrochloric acid in the stomach? – It inhibits peristalsis. – It creates an optimum acidity. – It prevents relaxation of the lower esophageal sphincter.

What is the benefit of HCl?

Hydrochloric acid, called HCl by chemists, is known to help break down protein in the stomach before the protein can be absorbed in the intestines. Allergies generally occur when inadequately broken down protein is absorbed from the intestines.

How does hydrochloric acid facilitate the function of pepsin quizlet?

The enzyme pepsin breaks down proteins in the stomach. The pepsinogen that is created by the chief cells in inactive until it comes in contact with the hydrochloric acid. It then turns into pepsin and breaks down the proteins.

What is the role of pepsin in the body?

An enzyme made in the stomach that breaks down proteins in food during digestion.
