PRODUCT DESCRIPTION

The compound hydrogen peroxide, H2O2, is a byproduct of metabolic reactions in most living lings. However, hydrogen peroxide is damaging to delicate molecules living inside cells. As a result, nearly all organisms, such as potatoes, contain the enzyme peroxidase, which Students will detect this reaction by observing the oxygen bubbles generated.
Problem: Does the enzyme peroxidase work in cold temperatures? Does the peroxidase work better at higher temperatures? Does peroxidase work after being frozen or boiled?
Various (pre-determined) temperatures will be tested during this lab.
Students will make a hypothesis regarding how they think temperature will affect the rate at which the enzyme peroxidase breaks down hydrogen peroxide. They must consider both low and high temperatures.

This is a wonderful, hands-on lab for any age science class! If you're feeling brave and want to see an even more dramatic reaction, use liver instead of potatoes!
