Digestive Enzymes Flashcards
1
Q
gastrin
A
Protein Digestion
- hormone that stimulates gastric acid release in the stomach to lower pH
- when food is ingested
2
Q
pepsin
A
Protein Digestion
- protease in stomach that cleaves polypeptides into large peptides
- when pH is lowered
3
Q
secretin
A
Protein DIgestion
- protein in duodenum that releases H2CO3 to neutralize pH
- when stimulated by low pH
4
Q
CCK
A
Protein Digestion
- protein in duodenum that activates proteases and peptidases
- when peptides arrive in duodenum from stomach
5
Q
Trypsin
A
Protein Digestion
- protease in duodenum that cleaves large peptides into small peptides
- when stimulated by CCK
6
Q
Chymotrypsin
A
Protein Digestion
- protease in duodenum that cleaves large peptides into small peptides
- when stimulated by CCK
7
Q
Elastase
A
Protein Digestion
- protease in duodenum that cleaves large peptides into small peptides
- when stimulated by CCK
8
Q
Aminopeptidase
A
Protein Digestion
- exopeptidase in duodenum that cleaves small peptides into AA
- when stimulated by CCK
9
Q
Carboxypeptidase
A
Protein Digestion
- exopeptidase in duodenum that cleaves small peptides into AA
- when stimulated by CCK
10
Q
Serpin
A
Protease Inhibition
- irreversible (suicide) inhibitor for permanently inactivating a single protease by binding to the protease and changing its active site
11
Q
Benzoate
A
Used to treat people with urea cycle enzyme deficiency
