Enzymes as Catalysts for Starch Digestion
kit #25R
The basic concept behind this engaging kit is that all living organisms must alter nutrients in order to make them usable. Colorful controlled experiments let students observe factors affecting enzyme activity while studying catalysis in an organic reaction. Tests are performed in drop quantities using the Lab-Aids Chemplate.
This kit is designed for use with six groups of four students. If any of your classes have more students than this kit is designed to accommodate you can obtain extra components by obtaining 25REL kit(s), each of which contain enough materials for one additional student group.
- Compare the role of an enzyme to that of a reacting substance
- Study the effect of enzyme concentration on rate of reaction
- Observe the effect of time and temperature on enzyme reaction
