B) Draw a graph to illustrate this general relationship. This graph can be general but should still have a title (1 point) and labels for the axes (2 points), and a line (1 point) Scan or photograph your graph and insert the image in the space below. (part b = 5 points)

a

8. A) Design an experiment to determine the optimal temperature for enzyme function, complete with controls. B) Where would you find the enzymes for this experiment? C) What substrate would you use? (part a = 7 points, part b = 3 points, part c = 3 points)
