The Enzymes in Action Kit© creates catalytic connections with models. The kit’s colorful foam pieces represent enzymes, which speed up chemical reactions within cells, and substrates, the small molecules upon which enzymes act. The protein model kit allows you 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. 

Each 3-group set contains 30 foam pieces (6 gray enzymes, 3 red substrates, 3 tan incompatible substrates, 3 purple competitive inhibitors, 3 blue noncompetitive inhibitors, and 6 green pieces to show catabolism and 6 orange pieces to show anabolism) and 3 sheets of stickers.
