Chemical processes, their rates, and whether or not energy is stored or released can be understood in terms of the collisions of molecules and the rearrangements of atoms into new molecules, with consequent changes in the sum of all bond energies in the set of molecules that are matched by changes in kinetic energy.

RG071003	During photosynthesis, energy is required to separate atoms of the reactants. This amount of energy is greater than the amount of energy released when atoms connect to form the products.
RG212001	If the chemical energy of the products of a chemical reaction is greater than the chemcial energy of the reactants, energy was taken in from the surroundings because the amount of energy required to break bonds of the reactant molecules is greater than the amount of energy released when bonds of the product molecules are formed.
