Broken down in the carbohydrate food.
Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. Carbohydrates are an important energy source, but must be broken down to be absorbed out of the digestive tract. In this lesson, you will learn how disaccharides and polysaccharides are broken down to monosaccharides through a process called hydrolysis. There are polysaccharides that your body cannot break down called cellulose. But cellulose is still valuable because it provides your body with fiber. Fiber helps the body move food through the digestive tract, somewhat like a scrub brush. To unlock this lesson you must be a Study.com Member. PRACTICE EXAM 5.

ANSWERS. Digestion is the. absorption of nutrients suspended in water. conversion of glycogen to glucose. chemical and mechanical breakdown of food for absorption into the body. churning of food in the stomach and intestine. Mouth. Carbohydrate digestion begins in the mouth. The salivary glands in the mouth secrete saliva, which helps to moisten the food. The food is then chewed while the salivary glands also release the enzyme salivary amylase, which begins the process of breaking down the polysaccharides in the carbohydrate food. Large Intestine (Colon). Carbohydrates that were not digested and absorbed by the small intestine reach the colon where they are partly broken down by intestinal bacteria. Fiber, which cannot be digested like other carbohydrates, is excreted with feces or partly digested by the Most carbohydrate foods contain many saccharides linked together, which are known as polysaccharides. Carbohydrate digestion begins in the mouth and is complete when the polysaccharides are broken down into single sugars, or monosaccharides, which can be absorbed by the body. Large Intestine (Colon). Carbohydrates that were not digested and absorbed by the small intestine reach the colon where they are partly broken down by intestinal bacteria. Fiber, which cannot be digested like other carbohydrates, is excreted with feces or partly digested by the In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. When the pyloric sphincter valve opens, chyme enters the duodenum where it mixes with digestive enzymes from the pancreas and bile juice from the liver and then passes through the small intestine, in which digestion continues. When the chyme is fully digested, it is absorbed into the blood. Rating Newest Oldest. Best Answer: Monosaccharides, but sometimes there is an intermediate stage where they are di-or tri-saccharides which are then broken down into monosaccharides.  When you eat, your body takes disaccharides and polysaccharides, and it breaks them down into monosaccharides. It is necessary for this breakdown to occur so the sugar units are small enough to be absorbed out of your digestive tract and into your bloodstream. There are polysaccharides that your body cannot break down called cellulose. But cellulose is still valuable because it provides your body with fiber.

The digestive system is a tube through which food passes from the mouth where food is ingested to the anus where it is egested. It consists of a series of organs, each with a distinct structure and function. During the digestive transit food is broken down into substances suitable for absorption into the bloodstream. The gut wall has the same basic structure along its length. There are three main layers: 1  An outer, muscular layer. 2  Circular and longitudinal layers of smooth muscles are present
