For example, electrical energy, light energy, and heat energy are all different types of energy. While these are all familiar types of energy that one can see or feel, there is another type of energy that is much less tangible. To appreciate the way energy flows into and out of biological systems, it is important to understand more about the different types of energy that exist in the physical world.

A negative change in free energy also means that the products of the reaction have less free energy than the reactants, because they release some free energy during the reaction.

This requires work- or more formally, energy. This reading covers energy, energy transactions, defines G, and defines ∆G (the change in energy available to do work). It also describes a core concept for this course: the "Energy Story".

A cell’s metabolism refers to the combination of chemical reactions that take place within it. Catabolic reactions break down complex chemicals into simpler ones and are associated with energy release. Anabolic processes build complex molecules out of simpler ones and require energy. In studying energy, the term system refers to the matter and environment involved in energy transfers.

Exergonic reactions occur spontaneously (∆G < 0), while endergonic reactions require energy input (∆G > 0). Chemical equilibrium occurs when forward and reverse reaction rates balance, but most biological reactions avoid equilibrium by continuously using energy.
