5) Which acid is present in the stomach a) Nitric acidb) Hydrochloric acidc) Acitic acidd) None of these |
|
Answer» b) HYDROCHLORIC acid Explanation:Gastric juice is MADE up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice BREAKS down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The MUCUS covers the stomach wall with a protective coating. Together with the bicarbonate, this ensures that the stomach wall itself is not damaged by the hydrochloric acid. |
