PRODUCT DESCRIPTION

FREE Biology lab on enzymes. "Catalase: An Enzyme Common to Both Plants and Animals."

Click this link to view all of my FREE products


Catalase is an enzyme that is commonly found in plant and animal tissues. The function of the enzyme catalase is to break down the chemical hydrogen peroxide inside living cells. Because it is toxic, or poisonous, hydrogen peroxide would soon kill the cell if it were not removed or broken down immediately.

In this lab, the enzyme catalase will be compared to the catalyst manganese dioxide. Catalysts are similar to enzymes in that they speed up chemical reactions, but they are not specific for just one reaction.

NOTE: This product is also available in a bundled product called Biology Labs: 15 Must Do Labs for a Biology Class .

NOTE: This product is also available in a bundled product called Enzymes, Catalysts and the Chemical Reactions of the Cell



Materials needed: Fresh plant and animal tissue, Test tubes and racks, Boiled animal tissues, Manganese dioxide, 3% hydrogen peroxide solution, Sand, Mortar and pestle

I can't save these because of an encriptment issue. I don't know if it is my issue or the lessons. It looks really interesting and helpful. Thanks for offering it.

There have been over 4000 downloads and no one else has had a problem. Your computer must be treating the zipped folder oddly. If you will email me, I will send your the files directly via email.
