Introduction to Thermodynamics

? The living cell is a chemical industry in miniature

? The totality of an organism's chemical reaction is called metabolism

? Metabolism involves managing the matter and energy resources of the cell

Thermodynamics = Energy Transformations

? Free energy is the capacity to do work ? The work of cells depends on the ability to

transform energy from one type into another

? Kinetic energy is energy of motion, includes thermal energy (heat)

? Potential energy is stored energy that matter possesses because of its location or structure (includes chemical potential)

Chemical potential energy is a form of potential energy that molecules posses as a result of the arrangement of atoms in those molecules
