The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. (However, this is considered a controversy because non-cellular life such as viruses are disputed as a life form. See Non-cellular life.)
Hydrochloric acid is the primary digestive acid and has several roles in digestion. The acid prevents harmful bacteria from entering your system by sterilizing it. Another function of hydrochloric acid is to trigger the release of pepsin. You need hydrochloric acid to absorb minerals like magnesium, sodium and iron. Gastric acid is so strong that it could digest the stomach if not for a mucus lining protecting the organ.
Hydrochloric acid is secreted from the stomach because the enzyme pepsin, which breaks down proteins in the stomach, works best in acidic conditions. The acid also helps to k â¦ ill any bacteria in the food.The hydrochloric acid is actually secreted from the pits in the stomach wall called gastric pits.epsin breaks down proteins. The hydrochloric acid also helps turn the solid food into a liquid that makes digestion possible. In addition, the HCl being very acidic provides protective mechanism to the body by being anti-bacterial in action.
