An investigation to look at the effect of temperature on enzyme activity Introduction The success of living organisms is due to the cell's ability to make protein catalysts, or enzymes, each with precisely specified properties. Each enzyme has a unique shape containing an active site. This active site binds a particular set of other molecules (called substrates) in such a way as to speed up a particular one of the many chemical reactions that the substrates can undergo (by a factor of up to 1014). Like all other catalysts, enzyme molecules themselves are not changed after participating in a reaction and therefore can function over and over again. Enzymes are usually irreversibly damaged (or denatured) under certain conditions such as high temperatures above about 45oC. The pH affects the activity of enzymes, in a similar way to temperature. A pH that's much higher or lower than the optimum pH causes...
