galvanic cell
Otherwise known as a voltaic cell.
gamma emission
The release of energy.
Gay-Lussac’s Law
Gas law which states that the pressure of a given mass of a gas varies directly with the absolute temperature of the gas when the volume is kept constant.
Means splitting of glucose.
Gibbs free energy
A thermodynamic quantity that combines enthalpy and entropy into a single value that has been named after Josiah Gibbs, an American physicist. This value can be used to determine equilibrium constants.
Process that breaks down proteins and provides needed glucose for the cells.
Made up of long chains of glucose units.
gold foil experiment
