Answer:All of these choices are correct-d
Explanation:
Low pH of the stomach is effective because enzymes like Pepsin, break down food and work best in an acidic environment in the breakdown of proteins Also, a low pH stomach acid also triggers the release of other digestive enzymes from the pancreas, which also help break down carbohydrates,
The mechanism is such that Because most proteins start digestion in the stomach, the stomach cells secretes the zymogen pepsinogen which by activation by HCl in the stomach forms the Pepsin that break the peptide bond of amino acids helping digestion.
Low pH in the stomach, ie Gastric acid with a pH of less than 3 provides an unsuitable environment for for bacteria and parasites by killing them and preventing them from reaching the intestines which would have been responsible for many more illnesses.
The low pH of the stomach makes the environment favorable for the gastric enzymes to function. It also helps to activate essential enzymes and make the conditions acidic in the stomach to dissociate the food.
What is the function of the low pH of the stomach?
The pH of the stomach is essential for the digestion of several nutrients, which functions as the first line of defense against the invading viruses and bacteria. Stomach is a store house of strong acid, with a pH lesser in comparison to other parts of the digestive tract.
This low pH helps to activate gastric enzymes like activation of pepsin from pepsinogen, which further dissociates the proteins into smaller fragments, this facilitates the digestion of food. The low pH of the stomach makes the gastric enzymes to work appropriately and thus helps the food to get break down easily.
Thus, the correct answer is option D, that is, all the mentioned statements are correct.
