Factors that affect the rate of enzyme catalysisEnzymes exist in all living things. They are composed of amino acid polymers and are produced in living cells. Each cell contains several hundred enzymes that catalyze a large number of chemical reactions. Enzymes are known as biological catalysts because they greatly increase the rate at which reactions occur within living organisms, without being "used up" or carrying out the reaction in any other way. Enzymatic catalysis avoids having to increase the temperature in order to accelerate reactions within living beings. Such an increase in temperature would be fatal for the body. In this investigation, I intend to explore one of the factors that affect the rate of enzyme catalysis. My research in textbooks and on the Internet suggests that it depends on several factors: temperature, pressure, pH and concentration. After research and careful consideration, I decided to first examine how a change in temperature might affect the reaction rate. In order to design a suitable experiment and make a credible prediction, I first need to explore more closely how temperature is likely to affect the rate of catalysis. . Enzymes are specific: they only control one type of reaction; so I need to use a specific enzyme in my experiment, in order to find a clear way to measure the reaction rate. Although they are specific, all enzymes work very similarly and have similar properties. They are all globular proteins and are all biological catalysts, they increase the speed of a given reaction without being exhausted and their presence does not change the nature of middle of paper......it was a success, but it could be improved by the use of more precise equipment and better organization. Several hypotheses had to be formulated in this experiment. When such assumptions are made, additional work should be done to verify these assumptions. I had to assume that all enzymes worked the same, but further work could be done with different enzymes and reactions to verify this. Through the experiment, I measured the reaction speed at 10 degree intervals. I think further work should be done between 30 and 40 degrees to try to find the exact optimal temperature for enzyme catalysis. Working between these temperatures would allow me to plot a more accurate graph and explain the apparent slowing of the reaction rate increase between these two temperatures in my current results..
