Digestion Flashcards
Salivary Amylase
Produced: salivary glands
Functions: mouth
Reaction: starch -> Maltose
Pancreatic Amylase
Produced: pancreas
Functions: duodenum
Reaction: starch -> Maltose
Maltase
Produced: Intestinal glands
Functions: duodenum
Reaction: maltose -> 2 glucose molecules
Sucrase
Produced: intestinal glands
Functions: duodenum
Reaction: sucrose -> glucose, fructose
Lactase
Produced: intestinal cells
Functions: duodenum
Reaction: lactase -> glucose, galactose
Pepsin
Produced: gastric glands (chief cells)
Functions: stomach
Reaction: hydrolyzes specific peptide bonds
Trypsin
Produced: Pancreas
Functions: duodenum
Reaction: hydrolyzes specific peptide bonds and converts chymotrypsinogen to chymotrypsin
Chymotrypsin
Produced: Pancreas
Functions: duodenum
Reaction: hydrolyzes specific peptide bonds
Carboxypeptidases A and B
Produced: Pancreas
Functions: duodenum
Reaction: hydrolyzes terminal peptide bond at C-Terminus
Aminopeptidase
Produced: Intestinal glands
Functions: duodenum
Reaction: hydrolyzes terminal peptide bond at N-terminus
Dipeptidases
Produced: Intestinal glands
Functions: duodenum
Reaction: hydrolyzes part of amino acids
Enteropeptidase
Produced: Intestinal glands
Functions: duodenum
Reaction: converts trypsinogen and procarboxypeptidases to active form
Bile
Produced: liver
Functions: small intestine
Reaction: emulsifies fat
NOT AN ENZYME
When chyme is present
duodenum secretes CCK into blood
CCK
stimulates secretion of pancreatic enzymes and bile, and promotes satiety
