Essay

Many of the steps in the pathways described in this chapter are essentially irreversible (for A $\rightarrow$ B $\Delta$ G << 0). As a result, if the cell wants to carry out the reverse transformation, it must use a different pathway to go from B $\rightarrow$ 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).
