Digestion Flashcards
Chemical breakdown
Due to enzymes that hydrolize
Mechanical breakdown
Chewing
Substrates
Molecules acted upon by enzymes
Accessory organ
Secrete enzymes
Salivary glands
Contains amylase that splits starch into maltose
Pharynx
Goes to epiglottis and then trachea or esophagus
Stomach
Hydrochloric acid and pepsin
Hydrochloric acid
Denatures proteins and kills germs
Pepsin
Proteins
Duodenum
Bile duct and pancreatic duct
Gallbladder
Stores bile
Pancreas
Amylase, lipase, trypsin, sodium bicarbonate
Trypsin
Protein breakdown
Small intestine
Disaccharidases
Peptidases
Capillaries and lacteals in villi
Disaccharidases
Sucrase, maltase, lactase
Peptidases
Breaks into amino acids
Capillaries
Absorb monosaccharides and amino acids
Goes to liver through heptatic artery
Lacteals
Absorb digested lipids
Lymphatic system
Liver
Stores glycogen, detoxifies, breaks down hemoglobin to bile, removes amino functional group from amino acids
Large intestine
Remove water
Bacteria make vitamins
