Question

Where do enzymes break down food in the digestive system

Answer 1

1. Saliva is secreted to moisten food, protect the mouth from abrassions, buffer against acids in food, kill some forms of bacteria, and begin carbohydrate digestion with the enzyme SALIVARY AMYLASE.

2. Stomach: Stores up to 2 liters of food while mixing and digesting it. The epithelial cells secrete GASTRIC JUICES and HCl making the pH around 2.
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.

3. Small Intestine: Most hydrolysis of macromolecules occur in the small intestine. It is more than 6 meters in length. It has smaller diameter than that of the large 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

The bread will be broken down first by an enzyme in your saliva called salivary amylase. This enzyme breaks down any starch or complex carbohydrates into sugar. Next, the sugar and the rest of the Big Mac will enter your stomach and be broken down by the acids in your stomach. The chyme, or the remnants of your food, will enter your small intestine. The small intestine's roll is to absorb the nutrients in the chyme. After all the vitamins, minerals, and fats are absorbed, the remnants will enter your large intestine. The large intestine will absorb the liquid from the remnants of the chyme. The liquid will become...urine. The waste will become feces.

Answer 3

the first enzymes that begin to break down food is in your mouth. It's called salivary almase. It breaks food down into sugar. Next time you eat a saltine cracker, chew it up and keep it in your mouth for a few minutes and let the enzymes do their work. You'll be surprised how sweet like sugar the cracker is!

Answer 4

In the stomache big pieces of food are broken down and then enzymes go to work really breaking it down and the food is absorbed in the small intestine. Thats why the small intestine is so long and has so many folds-it needs lots of surface area to absorb all the nutrients it can!

Answer 5

Basically it is the different organs you have internally. There are glands that produce juices that break down and help digest the food you eat. The main two orgrans that help are the liver and the pancreas.

Answer 6

In the mouth
