|
|
What are the target sites fo the seven pancreatic enzymes?
|
duodenum of the small intestine
|
|
maltase, lactase, sucrase and three enzymes that are produced by what organ?
|
small intestine
|
|
What are the substrates for maltase, lactase, and sucrase?
|
maltose, lactose, sucrose
|
|
what are the end products for maltase, lactase, and sucrase?
|
2 glucose, glucose/galactose, glucose/fructose
|
|
Amylase is produced by what organ? what is the target site?
|
salivary glands and the pancreas, the tartget site is the mouth, and the duodenum
|
|
what enzyme does not target the duodenum?
|
pepsin, it targets the stomach
|
|
what does pepsin attach itself to? what does it break down?
|
protiens
|
|
pepsin attaches and breaks down protiens, afterwards, what does it produce?
|
peptides
|
|
amylase produces what end product?
|
amylose
|
|
what is the product for pepsin, trypsin, and chymotrypsin?
|
peptides
|
|
What are the end products for carboxypeptides, and lipase?
|
carboxypeptides produce 2 amino acids, and lipase produces 3 fatty acids and 1 glycerol
|
|
DNA'SE AND RNA'Se PRODUCE
|
nucleotides
|
|
what are DNA'se and RNA'se substrates?
|
DNA, AND RNA
|
|
gastrin, secretin, CCK, are enzymes or hormones?
|
hormones
|
|
what produces gastrin?
|
G cells found in the stomach
|
|
what is the target site of gastrin? and what is the action of the hormone
|
target site is the stomach, it stimulates the production of gastric juices
|
|
SEcretin is produced where? what does it stimluate?
|
it is produced in the liver, pancreatic duct and the stomach. IT stimulates the production of bile, rich HCO3 fluid and inhibits stomach contraction
|
|
cck is produced in what part of the small intestine?
|
duodenum of the small intestine
|
|
what is the target site of the cck?
|
pancreas, gallbladder and the sphincter of ODDI
|
|
what does cck stimulate?
|
stimulates production of enzymes, releases bile and even opens the sphincter of oddi
|
|
The digestive aids of the digestive system are
|
BILE, AND HCL
|
|
WHERE IS bile prodoced?
|
liver
|
|
where is HCL produced?
|
parietal cells of the stomach
|
|
What does bile do to fats?
what is the substrate of bile? |
emulsifies the fats. lipase
|
|
what does HCL do?
|
kills bacteria, activates pepsinogen, and denatures proteins
|
