Water is a polar molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge () near the oxygen atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms.
- Availability of an energy source: Energy is minimized when all concentrations are equal, so an uneven distribution of molecules is a form of potential energy, which can be used to drive other processes. One process is the transport of molecules from one side of a membrane to the other. The equation that describes the amount of energy required for this process is : , where R = 8.315*10 -3 KJ/mol, the molar gas constant, and T = temperature. When the molecules involved are charged, an electrical potential can build up.
