Reactions in cells must be regulated and one way to do this is using allosteric molecules. These regulators can activate enzymes or inhibit them. This tutorial explains exactly how allosteric regulation works using words, narration, and...

In this biology simulation, students discover what factors influence the action of enzymes on cellular work. Students will first explore the action of enzymes through a simulation in which their hands are the enzyme "toothpickase" and...

For this biology lab, students use pineapple juice as an enzyme, and jello as a substrate to illustrate an enzyme/substrate complex.
