Begins by describing the basic structure of atoms and how ions are formed as atoms gain or lose electrons.

Starts by explaining how polymers are synthesized out of smaller monomers through dehydration reactions that release H2O molecules in the process. The program goes on to look at the role of carbohydrates in energy storage and as structural building blocks; the use of lipids in synthesizing plasma membranes, fats and steroid hormones and structural materials; and nucleic acids use in storing information and transferring energy.
