synthesis ATP synthase couple the exergonic movement of H+ ions down a concentration gradient to the endergonic _______ of ATP from ADP and Pi outer and inner Mitochondria has 2 membranes: ________ unfavorable Reaction with a positive change in free energy are thermodynamically favorable reaction with a negative free energy(G) are thermodynamically Energy ability to do work coordinate diagram Change in the free energy of molecules in chemical reaction can...

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...
