What are the hormones that regulate digestion?

Answer 1

Stomach: Pepsin is an enzyme used to partially hydrolyze protein. Pepsin is released in an inactive form PEPSINOGEN. The pepsinogen reacts with HCl to form pepsin.
The hormone GASTRIN is secreted by the stomach cells to regulate the production of gastric juices.

Small Intestine: It is divided into 3 sections ( Duodenum, Jejunum, and ileum). Accessory Organs ( Pancreas, Liver, and Gall Bladder), add digestive enzymes, juices and hormones into the small intestine. As the acid chyme enters the duodenum (first 25 cm of the small intestine) a hormone called SECRETIN is released from the intestinal walls to siginal the pancreas to release a bicarbonate solution which neutralizes the acid.
The hormone CHOLECYSTOKININ (CCK), is released from the intestinal cells causing the gall bladder to release bile. It also causes the pancreas to release its digestive enzymes. The hormone ENTEROGESTRONE is also secreted to slow down peristalsis. Protein Digestion: Trypsin and Chymotrypsin are enzymes that break bonds next to specific amino acids. Carboxypeptidase splits off one amino acid at a time.
This enzyme works on the end with the free carboxyl group. Aminopeptidase works in the opposite direction. All the above enzymes are secreted in an inactive form. They are activated by the hormone ENTEROKINASE. Fat Digestion: Bile emulsifies fat. This creates a larger surface area for the enzyme lipase to digest it. Carbohydrate Digestion: Disaccharide digestion is under the control of the enzymes maltase, lactase, sucrase.

Answer 2

Hormonal Control Of Digestion

Answer 3

There are three main ones. They are as follows,gastrin,secretin, and cholecystokinin/pancreozymin. When food enters the stomach, the wall of its pyloric end (the area at which the stomach joins the small intestine) releases a hormone called gastrin, which promotes the flow of acid from the gastric glands in the stomach. These glands also release pepsinogen, which is the inactive form of the protein-digesting enzyme pepsin, but this process is primarily under nervous control. The entry of the acidified stomach contents into the first part of the small intestine (duodenum) releases secretin and cholecystokinin/pancreozymin. Hope this helps.

Answer 4

The hormones that regulate digestion are first produced as zymogens in the pancreas. A zymogen is an inactive form of the hormone. For example, the pancreas creates pepsinogen which later become activated as pepsin.

This is crucial. If this pathway did not occur, the hormone produced would begin digesting the organ that created it.
