Final answer:
Enzymes do not change the magnitude of free energy difference (ΔG) between the reactants and the products, and do not affect the final equilibrium. They only change the rate of the reaction by lowering the activation energy required.
Step-by-step explanation:
Enzymes do not change the magnitude of free energy difference (ΔG) between the reactants and the products, and do not affect the final equilibrium. Enzymes only change the rate of the reaction by lowering the activation energy required for the reaction to occur. They accomplish this by binding to the reactant molecules and properly orienting them for the reaction to take place more easily. Enzymes are considered organic catalysts and they do not change the free energy of the reactants or products.
