1. Chemical reactions are reversible; they can proceed in both the forward and reverse directions. If the ΔG° for the reaction Y→X is energetically favorable, how can you explain the fact that not all of the Y molecules will be converted to X molecules?

2  Enzymes A and B catalyze different reactions, but use the same reactant molecule as a substrate. The graph in Figure Q3-47 presents the reaction rates observed when enzyme A and enzyme B are mixed together in a single test tube containing molecule X. What are the Vmax and the apparent Km values for each enzyme under these conditions? How might these values change for enzyme B if it were analyzed in the absence of enzyme A? Explain your answer.
