Ch. 24 The Carbohydrate Digestion & Absorption 1. The process of digestion that involves breaking down food with saliva, amylase, enzymes in the small intestine, and tools of teeth enables the body to digest into the stomach and intestines. 2. a. It begins in the mouth where the salivary glands allow it to soften where it can be easily swallowed as the salivary glands release the amylase to break down the carbs. b. Salivary amylase is involved and the pancreas secretes amylase while the pancreatic juice in the small intestine is adept for neutralizing gastric gas. Amylase also works with glycogen and starch to break it down. 3. Salivary amylase breaks down the starch and glycogen into alphadextrins, maltotroise, along with maltose where it can be further used. It is broken down by secretion. 4. The stomach acid has a strong pH level that is sufficient for destroying salivary amylase, which is no longer required. Also, saliva’s capability is low, therefore it is difficult to produce that much saliva to break it all down. 5. a. The pancreas assists by breaking down carbohydrates and getting rid of amylase by flushing it into the duodenum and supplying a rich infusion of carboxypeptidases along with endopeptidase.
