To explain why most enzyme-catalysed reactions proceed quickly Concept introduction: Enzymes are bio-catalysts that accelerate chemical reaction . Enzyme accelerates the rate of the reaction by lowering the energy of activation. The rate of an enzyme catalysed reaction is several times faster than an un-catalysed reaction. An enzyme accelerates both forward and reverse process to similar extent. An enzyme does not change the free energies of the initial and final states. The free energy of the reaction, ∆G , remains unchanged in the presence of an enzyme, so the relative amounts of reactants and products at equilibrium are unchanged. So, there is no change in the equilibrium constant of the enzyme-catalysed reaction.
