Question
**6.** If enzymes catalyze both the forward and reverse reactions, but do not change the equilibrium of a reaction, how could the reverse reaction for 'S ⇌ P' (pictured on the right) ever happen if it is unfavorable?

**Graph Explanation:**

The graph on the right displays the free energy changes in a reaction where 'S' is converted to 'P'. The y-axis represents Free Energy, and the x-axis represents the progress of the reaction. The curve starts at 'S', rises to a peak (activation energy), and then falls to 'P'. The free energy for 'P' is lower than that for 'S', indicating that the forward reaction is energetically favorable. The peak signifies the energy barrier that must be overcome for the reaction to proceed.
