-the secretion of hydrochloric acid and pepsin is stimulated. -gastric activity is stimulated in response to food increasing the pH of the stomach’s contents. -all of these take place in the gastric phase.
The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen, and in infancy rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis.
The active process that occurs when materials enter the digestive tract via the mouth is _____.
the mouth, the stomach, the small intestine, the large intestine
A series of disaccharidases enzymes that are released by intestinal epithelium digest disaccharides into monosaccharides. ii. Digestion of Proteins. Proteins are taken into the body from a number of dietary sources. Pepsin secreted by the stomach catalyzes the cleavage of covalent bonds in proteins to produce smaller polypeptide chains.
What Is The Digestive System? It is a group of organs in the body which work together to digest food. Digestion is the process by which our body breaks down food …

Digestion begins in the stomach with the action of pepsin. Pepsin is converted from pepsinogen by other pepsin molecules that are activated by HCl acid secreted by parietal cells.
12.12.2015 · The stomach also contains acid, which can also break down starch. The breakdown of starch can be carried out in the laboratory using acid or amylase. Enzymes such as amylase act as biological catalysts in the breakdown of complex food molecules into …

the stomach, pepsin,breaks the protein down into polypeptides in the small intestine- enzymes from the pancreas, trypsin and chymotrypsin break down the large polypeptides into smaller chains finally aminopepidase breaks down the small polypeptides into individual amino acids ready for absorption
There is no further digestion of chyme, as the stomach produces acid which destroys bacteria in the food and stops the action of the salivary amylase. In the Pancreas and Small Intestine After being in the stomach, the chyme enters the beginning portion of the small intestine, or the duodenum.
After people eat foods containing disaccharides, the stomach and small intestine break them apart. The small intestine absorbs the resulting monosaccharides, sending them into the bloodstream and ultimately to the liver, which converts them all to glucose.
