The cells of the stomach make an pro-enzyme called pepsinogeen. When pepsinogeen is secreted in the acidic (pH 2-3) environment of the stomach it transforms into pepsine, an enzyme wich breaks down proteins. If pepsine was made directly in the cells, it would destroy the cell before it would secreted in the stomach.
The acid level in the stomach helps break down food into smaller particles and kills harmful bacteria, aiding in the digestion process.
The pH level of stomach acid is around 1.5 to 3.5. This highly acidic environment helps break down food and kill harmful bacteria in the stomach, aiding in digestion.
Acid is found in the stomach, because the acid helps in digestion.
The stomach produces hydrochloric acid to aid digestion.
Hydrochloric acid is an acid. It is a strong mineral acid produced in the stomach to aid in digestion and has a pH level around 1-2.
Enzymes, they are responsible in chemical digestion.
Stomach acid refers specifically to the acidic fluid produced in the stomach to aid digestion. "Acid" is a more general term that can refer to a variety of substances with acidic properties, not necessarily related to digestion.
