1. Have students do library research on enzymes
involved in digestion. For
example, amylase catalyzes the
breakdown of starch; lipases catalyze the
breakdown of fats, etc.
2. Have students talk with physicians about Inborn Errors
of Metabolism. Two
common examples are phenylketonuria
and galactosemia.
3. Many states have laws that require the screening for
certain enzyme defects
in the newborn. Have students visit
state or local health departments to
learn about their policies.
4. Many animals (horses, cows, goats, termites, etc.)
have bacteria in their
intestinal system that produce the enzyme
cellulase. This enzyme breaks
down cellulose and permits these animals
to digest grass, wood, paper, etc.
Unfortunately, humans do not have the
bacterium that produces this
enzyme. Have students discuss the theoretical
ramification if this enzyme
could somehow be made available to humans.
5. All vitamins (except A, D, E, K) serve as enzyme activators
in biochemical
reactions. Have students do library
research to learn more about the specific
role of each vitamin.
6. Try gelatin (JelloTM) prepared with fresh
pineapple and also with canned
pineapple. Why does the preparation
made with fresh pineapple not gel?
7. Have students prepare reports on the importance of enzymes
in cooking or
home products.
