CHEMICAL DIGESTION
3
ENZYMES FUNCTIONALITYSubstrate combines with enzyme.
Provides energy to break down substrate by the addition of water = hydrolyses
Enzymes can be used over and over.
Work at specific pH.
4
Carbohydrates are always broken down from a poly saccharides to smaller disaccharides to eventually monosaccharides USING CARBOHYDRASES


Proteins are broken down from protein to smaller polypeptides to eventually amino-acids USING PROTEASES



Fats are broken down from large globules to fatty acids and glycerol USING LIPASES
5
DIGESTIVE SECRETIONSMOUTH = SALIVA CONTAINING CARBOHYDRASES
STOMACH = GASTRIC JUICE CONTAINING PROTEASES
PANCREAS = PANCREATIC JUICE CONTAINING CARBOHYDRASES AND PROTEASES
SMALL INTESTINES = INTESTINAL JUICE CONTAINING CARBOHYDRASES, PROTEASES AND LIPASES.
