Provide an explanation for the following observations;(a)fat are broken down into fatty acids and monoglycerides in the intestinal lumen but appear later in the blood as fat droplets.(b)how bile acids the digestive process even though it contains no enzymes .

Under what conditions does the active functioning of pancreatic lipase occur? What is its mechanism of action?

Identify the component of the GPAT (general plan of the alimentary tract) of the stomach Choose one from the following: (A) lamina propria (B) submucosa (C) muscularis mucosa (D) serosa (E) muscularis externa

(a) List the three major vessels of the portal triad, and describe the location of this triad with respect to the liver lobule. (b) Name three organelles that are abundant within hepatocytes, and explain how each of these organelles contributes to liver functions.

a) What is the general function of all enzymes that are involved in the digestive process.b) Use the Table below to summarise the function of 6 named digestive enzymes that are either secreted from specific regions of the gastrointestinal system, or part of the intestinal brush border.  Enzyme Site of secretion / Action Function (to include substrate and product formed)

What is the flow of blood and bile through the liver and the structural makeup of the liver lobule?

Mention the locations where the digestion and absorption of carbohydrates and proteins occur. Give examples of the chemical agents involved in the digestion of carbohydrates and proteins.

Blockage of the pancreatic duct prevents pancreatic enzymes from being delivered to the small intestine. What effect would youexpect this to have on cholecystokinin and secretin levels in the blood?

People who experience malabsorption frequently have the most difficulty digesting Considering the differences in , carbohydrate, and protein digestion and absorption, you offer explanation?

Describe protein digestion by location: mouth, stomach, small intestine, enterocyte, large intestine. Define zymogen/proenzyme. Describe each key enzyme in protein digestion (including how each are activated). Describe the function and importance of enteropeptidase. Describe the function and importance of trypsin. Know the difference between an endogenous and exogenous peptidase. Describe the functions of brush border peptidases and cytosolic peptidases. Describe absorption of peptides and absorption of amino acid (they are different). Describe different fates of amino acids once they are absorbed and released into circulation. Describe what can happen if protein is not absorbed properly.
