8. Many of the steps in the pathways described in this chapter are essentially irreversible (for A → BAG < 0). As a result, if the cell wants to carry out the reverse transformation, it must use a different pathway to go from B → A. For each of the enzymes on the left, pick the enzyme on the right that carries out the reverse transformation (not necessarily the reverse reaction).
