catalysis
catalysis The acceleration of a chemical or biochemical reaction that is brought about by the action of a catalyst. The catalyst, which is not affected by the overall reaction, acts by either lowering the activation energy of the reaction through a reorientation of molecules in collision, or by facilitating an alternative mechanism that has a different activation energy. Enzymes are naturally occurring catalysts which are universally present in all living cells. Enzymes are generally much more efficient and more specific than other catalysts.
