2 What do you know? What questions do you have? Draw and label an annotated diagram of the digestive system.

4 Chemical digestion must occur at body temperature!

5 Digestion Insoluble Food Molecule Soluble Products

6 EnzymeSubstrateProductsOptimum pH Pancreatic Amylase MaltoseGlucose7-8 EndopeptidasePolypeptidesAmino Acids8 Pancreatic Lipase TriglyceridesFatty Acids & Glycerol 7 NOTE: Enzymes are also released in the mouth and stomach to begin preliminary chemical breakdown. All macromolecules consumed can be digested, with the exception of cellulose (fiber) from plant cells. Cellulose is excreted without being digested.

7 What do you know? What questions do you have?
