Term
| Three characteristics of Albumin |
|
Definition
| This protein is synthesized in the liver, acts as a specific transport protein in the blood and is a regulator of blood osmolality |
|
|
Term
| This condition is required to activate pepsinogen |
|
Definition
| A low pH/high [H+] is necessary to active this digestive enzyme |
|
|
Term
| Two common examples of pancreatic enzymes |
|
Definition
| Proteases and phospholipases are two examples of these |
|
|
Term
| Abnormal or pre-mature proteolytic activation of pancreatic enzymes can lead to this condition |
|
Definition
| Pancreatitis is a consequence of this |
|
|
Term
| Pancreatic enzymes are normally active only at this location |
|
Definition
| These enzymes are only active in the lumen of the small intestine |
|
|
Term
| Alpha-amylase is found at these two locations in the body |
|
Definition
| The oral cavity and pancreas have isozyme |
|
|
Term
| These intestinal enzymes are bound to the mucosal cell membrane |
|
Definition
| Isomaltase, maltase, lactase and sucrase are found here |
|
|
Term
| These are 4 pancreatic zymogens |
|
Definition
| pro-elastase, pro-carboxypeptidae, trypsinogen and chymotrypsinogen |
|
|
Term
| These enzymes are found in the small intestine |
|
Definition
| Amino peptidases are found here |
|
|
Term
| General degredation pathway of dietary purines |
|
Definition
| broken down by cells of intestinal mucosa, converted to uric acid released into the blood, excreted by the kidney |
|
|
Term
| Lipid digestion requires this |
|
Definition
| Dietary bile salts are needed by this organ |
|
|
Term
| These two components are important for the solubility of cholesterol in bile |
|
Definition
| Conjugated bile salts and Phosphitidylcholine are important for this |
|
|
Term
| Chylomicrons absorb these molecules |
|
Definition
| Fatty acids and fat-soluble vitamins are taken up by these lipoproteins |
|
|
Term
| Deficiency in conjugated bile salts leads to this condition |
|
Definition
| Gallstones and Steatorrhea |
|
|
Term
| Deficiency in Vitamin A leads to this condition |
|
Definition
| Night blindness is a consequence of this dietary deficiency |
|
|
Term
| The oral cavity is where digestion of these molecules begin |
|
Definition
| Carbohydrates and TAG (w/ medium chain fatty acids) start their breakdown here |
|
|
Term
| A general pathway for DNA/RNA degredation in digestion |
|
Definition
Stomach: Low pH denatures DNA/RNA
Small intestine (enzymes from pancreas):
- Nucleases break down strands to
oligonuceotides
- Phosphodiesterases break down
oligonucleotides to mononucletides
- Nucleotidases break down
mononucleotides to nucleosides
- Nucleosideases break down nucleosides
into nucleotides
- Nitrogenous bases are absorbed into
intestinal mucosal cells where the
majority of purines are converted
into uric acid |
|
|
Term
| A general pathway for lipid degradation in digestion |
|
Definition
Small intestine:
Bile salts emulsify lipids and pancreatic enzymes degrade them to their primary products -
Free fatty acids
2-monoacylglycerol
cholesterol
Primary components are combined with protein to form chylomicrons which are then transported into the lymphatic system |
