Potato catalase lab

catalase and hydrogen peroxide reaction

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.

Potato catalase optimum ph

The enzyme tested during this experiment was the enzyme catalase. Nearly all living things possess catalase, including us! Keep one section raw and at room temperature. In order to do so we tested for the presence of organic molecules. For further information, consult your state's handbook of Science Safety. In this lab the chemical used was hydrogen peroxide because it can be broken down by catalase. The reaction is exothermic. The room temperature potato produced the most bubbles because catalase works best at a room temperature. Dilute immediately before use and put in a clean brown bottle, because dilution also dilutes the decomposition inhibitor.

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.
