The polysaccharide form of this is too big for the body to simply break down directly. So‚ instead the body uses multiple forms of procedures to break down the molecule into a usable size‚ such as glucose. The body begins breaking it down with salivary amylase. This is the process of chewing it in your mouth. The disaccharides then go through intestinal digestion which break them down

The digestive system is regulated both by the Autonomic system and the Enteric nervous system.

Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary amylase is inactivated by stomach acid in the stomach and to a small extent‚ it continues breaking down starch (but there’s no enzymatic activities on carbohydrates in the stomach). An intestinal enzyme‚ pancreatic amylase‚ continues the activity

In the mouth‚ teeth act as a tool that mechanically reduced size of food into small pieces. However‚ the tongue manipulates food bolus by pushing it for swallowing (Hoebler et al.‚1998). The last part of the oral cavity is salivary glands. In the salivary glands‚ it secretes saliva. Furthermore‚ enzyme that contain in the saliva is salivary amylase (common form

glands. The food is mechanically broken down. An enzyme named salivary amylase breaks starch into chunks of glucose called dextrins and maltose(disaccharide maltose). Once the food reaches the stomach‚ the acid in the stomach inactivates all salivary amylase. Carbohydrate digestion is not conducted the stomach for this reason. Before the food approaches the small intestine‚ the pancreas secretes pancreatic amylase. The pancreatic amylase digests starch into maltose. The enzymes maltase‚ sucrose‚ and

Group Members: Johnny Nguyen‚ Therese Pham‚ Linda Tang Name of Enzyme You are Investigating: Amylase Brief Background: Amylase is a digestive enzyme‚ produced mainly by the salivary glands and the pancreas‚ to break down starch in food into smaller carbohydrate molecules and disaccharides such as maltose. It can be found in humans and some other mammals. Some plants and bacteria may also produce amylase. After being broken down into smaller carbohydrate molecules‚ it can be converted into a monosaccharide

and premolars‚ and mixed with saliva by the tongue. The saliva has been produced by salivary glands‚ which pour it into the mouth through salivary ducts. This process of introducing food into the mouth is called ingestion. Chewing breaks food into smaller particles so that chemical digestion can occur faster. This cutting and mixing is called mastication. Moreover‚ food is chemically digested by salivary amylase (carbohydrase) in saliva which is an enzyme (biological catalyst) which breaks down

The body is made up of a number of systems that all interlink and produce everything we need in order to survive. Within the body there is the digestive system; the circulatory system‚ the nervous system‚ the muscular system‚ the skeletal system and the reproductive system. These systems are all part of one another and they share organs‚ tissues and cells and that is how they interlink. The diagram above shows each system and where they are located in the body. Each system is shown in a different

The Mouth: This is where the digestion of food starts‚ even before you take a bite of a Cheese Sandwich‚ the smell of it triggers the salivary glands in your mouth to create saliva‚ making your mouth water; when the food is in your mouth‚ the saliva increases. The food is broken down into small pieces by chewing‚ which are then small enough to be digested. More saliva is produced to begin
