   • Accomplish catalysis without being consumed in the reaction.

   • Catalyzes a specific chemical reaction. 

The Enzyme in Action Kit© allows your students to explore how enzymatic reactions occur. They will use the model pieces in the kit to:

   • Simulate enzymatic actions.

   • Explain enzymatic specificity.

   • Investigate 2 types of enzyme inhibitors used in regulating enzymatic activity.

   • Examine how an enzyme may affect activation energy.
