Digestive enzymes in the gut include proteases, which digest proteins. Why don’t these enzymes digest the stomach and small intestine, which are partially composed of protein?

Which of the following types of movement is responsible for the mixing of food in the GI tract? Group of answer choices Deglutition Mass movement Peristalsis Segmentation In the digestion of lipids, a chylomicron contains Group of answer choices Both monoglycerides and fatty acids Monoglycerides Fatty acids Triglycerides Which of the following components of digestion is responsible for the chemical breakdown of foods? Group of answer choices Chewing Enzymatic hydrolysis Dissolving Emulsification Which of the following is a hormone that stimulates the pancreas to secrete bicarbonate? Group of answer choices Cholecystokinin Secretin Gastrin Glucose-dependent insulinotropic peptide

Which of the following digestive enzymes is incorrectly matched with it's substrate and product?   pancreatic amylase: starch --> maltose   pepsin: protein --> amino acids   lipase: fats --> glycerol and fatty acids   peptidase: short polypeptides --> amino acids   salivary amylase: starch --> maltose

What structural modification of the stomach wall underlies the stomach’s ability to mechanically break down food?

Which digestive system activity actually moves nutrients from the outside to the inside of the body?

By watching this animation(http://openstaxcollege.org/l/foodgroups) , you will seethat for the various food groups—proteins, fats, andcarbohydrates—digestion begins in different parts of thedigestion system, though all end in the same place. Of thethree major food classes (carbohydrates, fats, and proteins),which is digested in the mouth, the stomach, and the smallintestine?

Put the following events in the correct chronological order in regards to digestion of protein as it flows through the digestive tract:   1. Activation of pepsin 2. Release of cholecystokinin 3. Release of pancreatic proteases 4. Gastric acid secretion

The enzymatic breakdown of large molecules into their basic building blocks is called: (a) absorption. (b) secretion. (c) mechanical digestion. (d) chemical digestion.

Follow the route food takes in the human GI tract and know the organs and their key functions including key fluids that are secreted. What actually does the stomach in humans do? (it is NOT the main place of digestion). What is bile (not a digestive enzyme) and where made, where secreted? What does pancreas contribute? Where is most of the food actually broken down into smaller molecular parts = digested? What is major role of large intestine (not digestion, not most absorption of nutrients) What are the muscular contractions that move it all?

Which types of macromolecules (protein, carbohydrate, fat, or nucleic acid?) can be enzymatically digested in the oral cavity, stomach small intestine?
