List the organs and structures of the digestive system that function in enzymatic hydrolysis and enzymatic dehydration synthesis and explain the details for each process
What is the process that makes the peptide bonds of proteins available to digestive enzymes? Digestion Denaturation Peptidase Hydrolyzing
The pH has a crucial role in the activation (or deactivation) of enzymes, which regulate digestion and avoid autodigestion (digesting yourself instead of the food). Describe the pH variations along the digestive tract and identify the organs responsible for these changes. Which enzymes are activated and deactivated during the course of the process? How exactly does this protect our digestive system? What other protections does the digestive system implement?
, Trace digestion and final absorption of a carbohydrate (starch) in the vertebrate gut, naming the carbohydrate-splitting enzymes, where they are found, the breakdown products of starch digestion, and in what form they are finally absorbed.Trace digestion and final absorption of a protein.
Digestion of proteins in the acidic environment of the stomach is carried out by the enzyme pepsin. A different enzyme, called trypsin, digests proteins in the neutral environment of our small intestine. The amount of each enzyme are the same and the amount of substrate is the same between the stomach and small intestine. Explain why our bodies use two different enzymes to digest proteins in the stomach and the small intestine.
Select all of the following that apply to CARBOHYDRATE DIGESTION. SELECT ALL THAT APPLY Mechanical digestion in oral cavity Chemical digestion in the oral cavity Mechanical digestion in the stomach Chemical digestion in the stomach Mechanical digestion in the small intestine Chemical digestion in the small intestine
A patient presents with a rare disorder called Zollinger-Ellison Syndrome. The patient has developed tumors in the small intestine that release hormones that stimulate the stomach to synthesize and secrete large amounts of HCL. How would this disorder disrupt normal digestive enzyme functions?
If proteases such as pepsin and trypsin digest protein, why do not they digest the stomach and small intestine, which are made from proteins?
Consider the following nutrients: (water, simple sugar (glucose), amino acid, and fatty acid). Describe where each one is absorbed in the small intestine and which mechanism (active transport, facilitated diffusion, or simple diffusion) drives their movement into the bloodstream. Please be detailed with your explanation
Describe the path of fats. How do they enter the cell and when do they go after they exit?
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.
You eat a cheeseburger. Describe the process by which the protein, carbohydrates and fats are broken down. Include the locations of each step. Explain how the final products of digestion are absorbed (separately for fat, protein and carbohydrates. Include where this happens, and where they go after. Explain what ingredients in the cheeseburger provide each type of nutrient.
