INTRODUCTION Enzymes are protein catalysts that speed up the rate of specific biological reactions. The first thing to notice in enzyme characteristics is that enzymes are almost all proteins, often globular proteins. They are long chains of amino acid units held together by peptide bonds. Enzymes are much more specific than simple catalysts. Numerous reactions occur within a cell and it is the enzyme’s job to assist by reducing the activation energy required to …showed first 75 words of 506 total…

CONCLUSION After the experiment, our original hypothesis, seeing if temperature has an effect on the activity of catalysts, our results showed that the hypothesis was not correct. The colder and hotter the temperate from each tube slowed down. However, colder temperatures did show some results; whereas heat showed no results. Among the temperatures tested, boiling water totally inactivated catalase.
