The Hydrogen Peroxide Breakdown

The Hydrogen Peroxide Breakdown 7. The Hydrogen Peroxide Breakdown Examining Factors that Affect the Reaction Rate of Enzymes Using a Graphing Calculator and Data Collection Device There are thousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions proceed too slowly to occur by themselves. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes, therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature of the cell. These catalysts are needed in only very small amounts because a single enzyme molecule can complete the same reaction thousands of times in one minute. Each enzyme is very specific and can only catalyze a certain reaction. The specific reaction catalyzed by an enzyme depends on the molecular structure and shape of a small area of the enzyme's surface called the active site.

carefully push the disks 1/2 to 1/3 of the way down the wall of the test tube. Repeat this procedure until you have four disks stuck to the inside wall of the test tube. 14. Place the stopper that is connected to the pressure probe onto the test tube. 15. Press . There should be 4 short beeps and the quick setup light will flash. The experiment
