Enzymes Introduction Introduce enzymes and what they are. 1 paragraph- Describe what an enzyme is. In your description you should focus on the class of molecules that enzymes belong to, the structure of enzymes, and how that structure contributes to their function You should also describe what it is that enzymes do. Describe how enzymes work as biological catalyst 1 Paragraph-Describe active site of an enzyme, how it interacts with its substrate, and how enzymes lower the activation energy of a chemical reaction. Introduce the enzyme catalase how enzymes act as biological catalyst. In this section you should describe the 1 Paragraph. Describe the reaction complete with equation that catalase catalyzes. Where is the enzyme found in the cell and why is it important to break down hydrogen peroxide. Describe how you are planning on measuring (quantifying) the catalase activity 1 Paragraph. Describe the use of guaiacol and the oxidation of guaiacol and how you will use it to measure the activity of the enzyme, What do you mean by enzyme activity? Describe the purpose of your experiment 1 Paragraph. Describe the purpose of your experiment, including what you hope to find out about catalase. Include at least two references in your introduction and have the reference formatted according to APA style

Explanation / Answer

All living things possess catalysts, or substances within them that speed up chemical reactions and processes. Enzymes are molecules that enable the chemical reactions that occur in all living things on earth. In this catalase and hydrogen peroxide experiment, we will discover how enzymes act as catalysts by causing chemical reactions to occur more quickly within living things. Using a potato and hydrogen peroxide, we can observe how enzymes like catalase work to perform decomposition, or the breaking down, of other substances. Catalase works to speed up the decomposition of hydrogen peroxide into oxygen and water. We will also test how this process is affected by changes in the temperature of the potato.

Materials

1 Potato

Hydrogen peroxide

Small glass beaker or cup

Procedure

- Divide the potato into three roughly equal sections.

- Keep one section raw and at room temperature.

- Place another section in the freezer for at least 30 minutes.

- Boil the last section for at least 5 minutes.

- Chop and mash a small sample (about a tablespoon) of the room temperature potato and place into beaker or cup.

- Pour enough hydrogen peroxide into the cup so that potato is submerged and observe.

- Repeat steps 5 & 6 with the boiled and frozen potato sections.

Observations & Results

Watch each of the potato/hydrogen peroxide mixtures and record what happens. The bubbling reaction you see is the metabolic process of decomposition, described earlier. This reaction is caused by catalase, an enzyme within the potato. You are observing catalase breaking hydrogen peroxide into oxygen and water.

You should have noticed that the boiled potato produced little to no bubbles. This is because the heat degraded the catalase enzyme, making it incapable of processing the hydrogen peroxide. The frozen potato should have produced fewer bubbles than the room temperature sample because the cold temperature slowed the catalase enzyme’s ability to decompose the hydrogen peroxide. The room temperature potato produced the most bubbles because catalase works best at a room temperature.

Conclusions

Catalase acts as the catalyzing enzyme in the decomposition of hydrogen peroxide. Nearly all living things possess catalase, including us! This enzyme, like many others, aids in the decomposition of one substance into another. Catalase decomposes, or breaks down, hydrogen peroxide into water and oxygen.
