Biological Molecules and Cellular Energy
Everything is made up of atoms. The subatomic parts of atoms consist of protons (positive charge), neutrons (no charge) and the electrons (negative charge). Because of the nature of these particles, bonds form (or ionic) and that lends itself to the building of molecules like proteins, carbohydrates, lipids and nucleic acids.

One of the main chemical compounds that our bodies depend upon is water. Water's behavior stems from its hydrogen bonding . . . this intermolecular forces lends itself to polarity. Polarity is the unequal distribution of electrons. This means that oxygen wants the electrons more so than the hydrogen atoms.
What else can we relate to chemistry AND biology? How do we make proteins? What role does Nucleic Acids play within our bodies?
How wonderful are plants?
Here is a great tutorial explaining the whole process of photosynthesis . . .
Here are some tutorials for better understanding the role of ATP and cellular respiration within living organisms . . .
What do cells need all of that ATP for anyway? Check out this tutorial for cell division . . .
