activation energy energy needed to get a reaction started Delta G (change in G - change in free energy) respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition results in decrease in activity of that enzyme, reaising activation enregy...
