Draw an enzyme reaction graph that do the following: a. Draw a graph showing the progression of a reaction without the presence of an enzyme. Put total energy on the y axis and reaction pathway (or course of reaction) on the x axis.
b. Add a line to show the progress of the same reaction with the presence of an enzyme.
c. Make this line visually distinct from the first one (e. g. - a different color, dashed instead of solid, etc.)
d. Add a key for the graph so that it's clear what each line represents.

Label the following features:

activation energy, reactant, and product.
