Each trial has different variable changes. When comparing pH levels to relative rate of reaction, the lowest and highest pH levels either worked slowly and sometimes not at all. This trend shows that there is a certain range of pH in which enzymes' production level is at its highest.While analyzing therelationship between temperature and relative rate of production, the relationship is very similar to pH levels. In high and low temperatures, the enzymes worked slowly or not at all. this is because the temperature also has a certain range in which it can function. How Enzymes Function Enzymes can only quicken reactions with certain reactants called substrates. Theses reactants fit like a lock and key into the activesite of the enzyme which holds them at the perfect position for quick reactions with lowactivation energy. Enzymes can take in thousands of reactions a second without everaltering itself. The factors that affect enzymesare pH levels and temperature. 0.000 0.005 0.010 0.015 0.020 0.025 0.030 0.035 0.040 0.045 0.050 0.055 0.060 Slope 0 5 10 15 20 25 30 35 40 45 50 55 60 Temperature(c) According to our data, at 5 degrees Celsius enzymes can function but not at top speed,at 25 degrees Celsius the enzymes work the fastest they did the whole lab, at 35 degreesthe enzymes work the slowest out of all thetrials, and at 55 degrees the rate of production was only slightly higher than 35 degrees.In conclusion, our data shows that 5 degreesand below will slow down the reaction. 35 degrees and above will start to denature theenzymes which will significantly slow down the reaction.
