<span>The answer is a. carbohydrates. The amount of potential energy in the molecule depends on the number of C-H bonds in the molecule. Carbohydrates have more C-H bonds. Thus, they can serve as energy storage. Other macromolecules have less C-H bonds. Thus, when energy is needed immediately, complex carbohydrates break down to simple carbohydrates and the energy is released.</span>
