Intracellular digestion
occurs within the cell
Extracellular digestion
refers to digestive process that ocurs outside the cell, within a lumen or tract
pharynx
leads food from mouth into esophagus
esophagus
- musclular tube leading from pharynx to the stomach by involuntary muscle contractions (peristalsis)
lower esophageal (cardiac) sphincter
- prevents regurgitation of stomach contents into esophagus
peristalsis
- involuntary movements of smooth muscle contraction
pyloric sphincter
regulates passage of chyme from stomach into the small intestine
parts of the small intesting
duodenum
jejunum
ileum
cholecystokinin (CCK)
- hormone secreted into blood by duoden in response to chyme
- stimulates secretion pancreatic enzymes and bile
lipase
hydrolyze molecules of fat into glycerol and fatty acids
enterogastrone
- hormone released by the duodenum
- inhibits sotmach peristalisis, thus slowing down release of chyme into small intestine
parasympathetic innervation
- stimulates digestion
sympathetic innervation
- inhibits digestion
hepatic portal vein
carries monosaccharides, aa, and fatty acids that diffuse into intestinal cappilaries to the liver
pancreatic juice
- alkaline fluid
- neutralizes acidity of chyme entering small intestine
- important because small intestine enzymes work optimally at netural or alkaline pH
Salivary amylase
- carbohydrate
- made in salivary glands
- funcions in mouth
- hydrolyzes starch to maltose
pancreatic amylase
- carbohydrate
- made in pancreas
- functions in small intestine
- hydrolyzes starch to maltose
maltase
- carbohydrate
- made in intestinal gland
- functions in small intestine
- hydrolyzes maltose to 2 glucose
sucrase
- carbohydrate
- made in intestinal gland
- functions in small intestine
- hydrolyzes sucrose to glucose and fructose
lactase
- carbohydrate
- made in intestinal gland
- functions in small intestine
- hydrolyzes lactose to glucose and galactose
pepsin
- protein
- made in gastric glands
- functions in stomach
- hydrolyzes specific peptide bonds
trypsin
- protein
- made in pancreas
- functions in small intestine
- hydrolyzes specific peptide bonds
- converts chymotrypsinogen to chymotrypsin
chymotrypsin
- protien
- made in pancreas
- functions in small intestine
- hydrolyzes specific peptide bonds
carboxypeptidase
- protein
- made in pancreas
- functions in small intestine
- hydrolyzes C-terminal peptide bond
aminopeptidase
- protein
- made in intestinal gland
- functions in small intesting
- hydrolyzes N-terminal peptide bond
dipeptidases
- protein
- made in intestinal glands
- functions in small intestine
- hydrolyzes paris of aa
enterokinase
- protein
- made in intestinal glands
- functions in small intestine
- converts trypsinogen to trypsin
bile
- lipids
- made in liver
- functions in small intestine
- emulsifies fat
- NOT AN ENZYME
lipase
- lipids
- made in pancreas
- functions in small intestine
- hydrolyzes lipids

stomach
location where bile is made
liver
Enzymes that function in mouth
salivary amylase
Enzymes that function in small intestine
pancreatic amylase
maltase
sucrase
lactase
trypsin
chymotrypsin
carbodypeptidase
aminopeptidase
dipeptidase
enterokinase
bile
lipase
Enzymes that function in stomach
pepsin
