Enzymes as Catalysts for Starch Digestion

This kit allows students to qualitatively and quantitatively observe the catalytic effects of enzymes on the breakdown of starch into sugar. In Part 1, students use Starch Indicator (Lugol’s) Solution to provide evidence that enzymes play a critical role in the breakdown of starch. Part 2, a teacher demonstration, shows that the breakdown of starch results in the production of glucose. In Part 3, student experiments provide evidence that the enzymes are catalysts for the process, not reactants. Optional extensions allow students to examine the effects of temperature and pH on the enzyme activity.
