Sugar/yeast ======> energy + carbon dioxide +alcohol Enzymes To measure the rate of reaction I will measure the amount of carbon dioxide produced within a certain time. This is the easiest product to measure and also the product to give the most accurate and reliable results. To measure energy or alcohol would need very expensive apparatus which isn't available and also wouldn't give such reliable results. Enzymes catalyse the rate of the growth of yeast so therefore we need to know what factors affect enzymes, they are: 1.

So as the temperature increases there is more heat energy...
