What we know Enzyme + substrate product Enzymes reduce the energy required to carry out the reaction. Enzymes can be denatured. There are factors that change the amount of product that is made. http://www.youtube.com/watch?v=CZD5xsOKres

Enzymes are catalysts

Goals: Answer this Question How does _______________ affect the amount of products made in one minute? Group 1: Change the amount of enzymes Group 2: Change the amount of substrate Group 3: Change the temperature Group 4: Change the pH Remember that you only change this factor.
