In this lab activity, students will investigate 3 factors that affect the rate of chemical reactions: denaturation, coenzymes, and competitive inhibitors. Students will perform a simulation of a chemical reaction with an enzyme represented by a hand, the substrate represented by pennies on the ground, and the chemical reaction represented by flipping the pennies over (one at a time) to be heads up on the desk. Each group will complete 4 trials before class data is collected for students to graph, analyze, and write a conclusion from. This is an excellent lab to help your students understand the effect of enzymes on biochemical reactions, and is great to use in a classroom with limited space and materials, because you don’t need much!
How can I use this?
- Practice for understanding enzymes and their effect on biochemical reactions
- As an inquiry investigation before providing any instruction on enzymes
