lactase
maltase

Question 2

enzymes for protein digestion

Answer 2

rennin
pepsin
pancreatic proteases (trypsin, chymotrypsin, carboxypeptidase)
brush border proteases (aminopeptidase, carboxypeptidase, dipeptidase)

Question 3

enzymes for lipid digestion

Answer 3

bile salts

pancreatic lipase

Question 4

salivary amylase

Answer 4

parotid and submandibular salivary glands –> mouth and esophagus

starch/polysaccharides –> smaller polysaccharides/disaccharides

Question 5

pancreatic amylase

Answer 5

acinar cells –> small intestine

starch/polysaccharides –> smaller polysaccharides/disaccharides

Question 6

lactase and maltase

Answer 6

brush border of SI –> small intestine

disaccharide (lactose, maltose) –> monosaccharide

Question 7

rennin

Answer 7

stomach of infancts –> stomach

coagulates milk proteins

Question 8

pepsin

Answer 8

stomach –> stomach

polypeptides –> smaller polypeptides

Question 9

pancreatic proteases (trypsin, chymotrypsin, carboxypeptidase)

Answer 9

acinar cells –> small intestine

polypeptides –> smaller polypeptides

Question 10

brush border proteases (aminopeptidase, carboxypeptidase, dipeptidasae)

Answer 10

brush border of SI –> small intestine

smaller polypeptides –> amino acids

Question 11

carboxypeptidase

Answer 11

pancreatic and brush border protease

breaks into amino acids from one end of peptide

Question 12

bile salts

Answer 12

hepatocytes in liver, stored in gall bladder –> small intestine

fat globules –> smaller globules

Question 13

pancreatic lipase

Answer 13

acinar cells –> small intestine

triglycerides –> fatty acids and monoglycerides

Question 14

pepsin not in small intestines because ….

Answer 14

ideal environment is acidic

brunner’s glands and pancreas neutralizes SI
