Digestive Enzymes Flashcards
What is salvary amylase? where is it produced?
(carbs)
Produced by the salvary glands. Breaks down carbohydrates (polysaccharides) into smaller polysaccharides.
Pancreatic Amylase
(carbs)
breaks down small polysaccharides into disaccharides. released into small intestines.
Disacharidases
(Carbs)
Disaccharides into monosaccharides. produced by epithelium in small intestines
Pepsin
(protein) Released as pepsinogen by the chief cells. Activated by HCL or pepsin. breaks proteins down into small polypeptides.
How do Pancreatic Trypsin and Chymotrypsin work?
cleave bonds adjacent to certain amino acids.
How do Pancreatic Trypsin and Chymotrypsin work?
(protein) further breaks down polypeptides into smaller polypeptides
Pancreatic Carboxypeptidase
(protein) smaller peptides into small peptides
Dipeptidases, Carboxypeptidase and aminopeptidase
(protein) Produced in epithelium of the small intestines. break down small peptides into amino acids.
How do Dipeptidases, Carboxypeptidase and aminopeptidase from the epithelium in the small intestines work?
They Split off one amino acid at a time working from each end.
Where does Nucleic Acid Digestion begin?
In the Small intestines with the release of Pancreatic Nucleases
Where does Carbohydrate Digestion begin?
Oral Cavity with salivary amylase
Where does the digestion of starches take place?
Oral Cavity with salivary amylase. (starches and glycogens are both carbs)
where does the digestion of Fats begin? Lipids?
Small intestines with Pancreatic Lipase. Lipids are fats
Pancreatic Nuclease
DNA and RNA into Nucleotides
Nucleotidases
Nucleotides into Nucleosides
Nucleosidases
Nucleosides into Nitrogenous bases, sugars, and phosphates.
Nucleosidases are produced where?
in the epithelium in the small intestine
Pancreatic Lipase
Fat (Triglycerides) into Glycerol, Fatty Acids, and Monoglycerides
What condition are the fats in when they are digested by pancreatic lipase?
They have already been broken (emulsified) into droplets by Bile and are coated with Bile salts.
