Students will time their results. Students will compare the time for objective 3 to the time when a variable is added. Students will compare their results with their lab partners' results. Students will graph and chart their results with the rest of the class. Students will see that starch is broken down to sugar in their mouths.
Enzymes are proteins that catalyze the chemical reactions of living cells.
They are composed of 200 to 1000 amino acid residues linked by a unique genetic code. The unique structure determines the function of the enzyme. The chemical that the enzyme attaches to is called the substrate. The enzyme transforms the substrate into products. In this case starch is broken down into sugar by the enzyme, Amylase, which is in saliva.
