what enzymes are secreted by the small intestine?
430338
Proteolytic enzymes, including trypsin and chymotrypsin, are secreted by the pancreas and cleave proteins into smaller peptides. Carboxypeptidase, which is a pancreatic brush border enzyme, splits one amino acid at a time. Aminopeptidase and dipeptidase free the end amino acid products.

As a digestive organ, the pancreas secretes pancreatic juice that contains digestive enzymes that assist the absorption of nutrients and digestion in the small intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.

Proteins are digested in the stomach and small intestine. Protease enzymes break down proteins into amino acids.

Answer and Explanation: Most digestive enzymes are produced in the pancreas and small intestine. The different types of enzymes are lipase, amylase, and protease.

The chyme then goes from the stomach into the first part of the small intestine, called the duodenum. This causes the pancreas to release pancreatic amylase. This enzyme breaks down the chyme into dextrin and maltose. From there, the wall of the small intestine begins to make lactase, sucrase, and maltase.

Bile is secreted into the small intestine where it has two effects: it neutralises the acid - providing the alkaline conditions needed in the small intestine. it emulsifies fats - providing a larger surface area over which the lipase enzymes can work.

Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases. From your stomach, these smaller chains of amino acids move into your small intestine.

Lipase enzymes break down fat into fatty acids and glycerol. Digestion of fat in the small intestine is helped by bile, made in the liver. Bile breaks the fat into small droplets that are easier for the lipase enzymes to work on. Bile is not an enzyme.

Pancreatic amylase is made in the pancreas and delivered to the small intestine. Here it continues to break down starch molecules to sugars, which are ultimately digested into glucose by other enzymes. This is then absorbed into the body's blood circulation through the wall of the small intestine.

Digestive enzymes are released, or secreted, by the organs of the digestive system. These enzymes include proteases that digest proteins, and nucleases that digest nucleic acids. Examples of digestive enzymes are: Amylase, produced in the mouth.

Pepsin is the primary enzyme found in gastric juice. Lipases, amylases, and proteases are secreted from the pancreas into the small intestine in response to food ingestion. These enzymes are responsible for most nutrient digestion.

Enzymes break the food into nutrients, that are processed in the large and small intestines. The small intestine absorbs the nutrients and send it to the bloodstream. It also does most of the Chemical Digestion, while there is absolutely no Mechanical Digestion.

Functions are digestion and absorption. Completed in the small intestine. Presence of chyme in the duodenum stimulates enzyme production in the small intestine. Accessory organs such as liver, pancreas and gallbladder also produce digestive enzymes.
990157
Pancreatic acinar cells synthesize and secrete almost all the digestive enzymes active in the lumen of the small intestine which are necessary for nutrient digestion. Both synthesis and secretion are highly regulated over both short and long time frames to insure an appropriate supply of digestive enzymes.

The digestive enzymes (such as amylase, lipase, and trypsin) are released from the cells of the acini and flow into the pancreatic duct. The pancreatic duct joins the common bile duct at the sphincter of Oddi, where both flow into the duodenum. The enzymes are normally secreted in an inactive form.

Digestive enzymes of diverse specificities are found in the saliva secreted by the salivary glands, in the secretions of cells lining the stomach, in the pancreatic juice secreted by pancreatic exocrine cells, and in the secretions of cells lining the small and large intestines.
