What will be an ideal response?
Consider an analogy between reaction-coupling and money. In a simple economy, barter provides a means of direct exchange of material goods
For example, the owner of a cow may have excess milk and need eggs, whereas a chicken owner has excess eggs and needs milk. Provided that these two people are in close proximity and can communicate, they may exchange or barter eggs for milk. But in a more complex economy, money serves as a mediator for the exchanges of goods or services. For instance, the cow owner with excess milk may not need other goods until three months from now, or may want goods from someone who does not need milk. In this case, the "energy" from providing milk to the economy can be temporarily "stored" as money, which is a form of "energy" used for many transactions in the economy. Using barter and money as analogies, describe two mechanisms that can serve to drive an unfavorable chemical reaction in the cell.
