Document Summary
Not all energy is equal (in its quality) High quality energy (potential) becomes low quality energy (random kinetic energy of the water molecule- heat) Living organisms convert high quality energy into low quality energy. The quality of energy depends on how much is free. Disorder system : can adopt many micro states. Increase of disorder ; aligned potential energy converted into the kinetic energy. The change in free energy determines whether a process occurs spontaneously. High delta g star= low rate of chemical reaction. Enzymes: lowers free energy to increase probability of collision. If we couple the hydrolysis of atp (negative) with positive reaction of glutamic acid to glutamine. The sum of delta g becomes negative therefore become favorable. Atp binding/hydrolysis can distort the 3d structure of proteins. The form of the protein changes and the distortion introduces strain energy. Many of the atoms pushed out from where they want to be ( minimum energy)
