4. Draw a free energy reaction coordinate diagram for both a generic endergonic and a generic exergonic reaction (label each). Make sure to label the x- and y-axes. Now label where reactants and products should go on the figure. Draw something that illustrates the free energy change for each reaction. Now write something like the following next to your figures: “reactants <—> products”. a. What do the reaction coordinate diagrams have to do with the text you just wrote? b. What...
