Look at the graph of enzyme activity below and answer the questions that follow. ***Textbook chapter 2 for answers 21, 22

21. What does this graph tell you about how temperature affects enzyme activity? Enzyme works best an optimal temp, in this example 49oC. If temp is too low or too high, the enzyme activity decrease.

22. Why do you think the activity of the enzyme declines after 40 degrees? The enzyme’s shape changes (enzyme is denatured), and the substrate (reactant of the enzyme) can no longer bind at the enzyme’s active site.

31. What is the activation energy of a chemical reaction?

the amount of energy needed to start the reaction

32. Do you think that the activation energy is the same for all chemical reactions? Why or why not? no because some chemical reactions may take more or less energy
