In order to do so we tested for the presence of organic molecules. Which potato sample decomposed the most hydrogen peroxide? A chemical reaction links monomers together occurs and releases a water molecule, this is called dehydration synthesis.
Reading and following the safety precautions of all materials used in a project is the sole responsibility of each individual. Catalase decomposes, or breaks down, hydrogen peroxide into water and oxygen.
This reaction is caused by catalase, an enzyme within the potato.
Preparation a Make just enough diluted hydrogen peroxide just before the lesson. Want to take a closer look? Which one reacted the least? Groups of three could work to collect results for 5 different concentrations and rotate the roles of apparatus manipulator, result reader and scribe.
