Energy must be added to the reactants to bring them into a transitional state (activation energy) Once a transition state is reached the reaction will occur spontaneously (downhill) The greater the activation energy required the less likely the reaction will proceed. The reactions of metabolism can proceed by themselves, but at a rate far too slow to support life. Catalysts: a. increase the rate of chemical reactions, b. are not altered by the reaction, c. do not change the final result of a reaction. The breakdown of atp into adenosine diphosphate (adp) and inorganic phosphate results in the liberation of energy.
