Although ATP supplies energy to an endergonic reaction, why is it not considered a fuel?
Define the following terms: (1) bioenergetics, (2) ender- gonic reactions, and (3) exergonic reactions.
Cells use primarily two ways of storing potential energy: 1) as concentration gradients and 2) in molecules. A) Explain how energy can be stored in these two forms and how it can be used to do other work. B) Propose an analogy that can explain each of these forms of energy storage using everyday items.
