AP BIOLOGY

Detailed explanation-1: -Some hydrolysis occurs in the small intestine, but most (approx. 90%) escapes digestion and is fermented in the large intestine after first being hydrolyzed by microbial enzymes to glucose, sorbitol, and mannitol.

Detailed explanation-2: -Small intestine is the main location for starch digestion and absorption. Small intestine can be divided into duodenum, jejunum, and ileum. Most starch is digested in the duodenum (receiving the digestive secretions from pancreas and liver), then absorbed at the jejunum and ileum.

Detailed explanation-3: -When you chew carbohydrate-rich foods, carbohydrase enzymes, such as amylase in your saliva, break down starch into sugar to give us the energy we need. Then protease enzymes in your stomach break down the proteins that will build new cells and repair damaged tissue.

Detailed explanation-4: -Most carbohydrate digestion occurs in the small intestine, thanks to a suite of enzymes. Pancreatic amylase is secreted from the pancreas into the small intestine, and like salivary amylase, it breaks starch down to small oligosaccharides (containing 3 to 10 glucose molecules) and maltose.
