Energy is the capacity to cause change. It can be transferred and transformed, but it cannot be created or destroyed (First Law of Thermodynamics). Every energy transfer or transformation increases the entropy (disorder) of the universe (Second Law of Thermodynamics).

In an endergonic reaction, the free energy of the products is higher than the free energy of the reactants ((AG > 0; energy is stored in the products), so the reaction is not spontaneous and additional energy must be supplied to make the reaction proceed.

In an exergonic reaction, the free energy of the reactants is higher than the free energy of the products (AG < 0). Energy is released to the environment, which overcomes the activation energy of the reaction and makes it spontaneous.
