In this experiment, chemical reactions take place in cells and are responsible for all the actions of organisms. Chemical reactions can consume energy (endergonic) or release energy (exergonic). Together, these reactions make up an organism 's metabolism. The chemicals taking part in these reactions are called metabolites.

In all reactions:

chemical bonds in the reacting molecules are broken; this takes in energy new chemical bonds form to make the products; this gives out energy
When a chemical reaction takes place energy is either taken in or released. This depends on the relative strengths of bonds being broken and bonds being formed.

In an exergonic reaction, energy is released to the surroundings. The bonds being formed are stronger
