Reaction coordinate free energy
WebNov 8, 2016 · Left: Reaction coordinate diagram for an enzyme-catalyzed reaction representing the mechanistic model we are considering. The free energy of activation, ΔG‡, which for our present purposes can be considered as equivalent to activation energy, is much lower for the catalyzed reaction compared with the uncatalyzed reaction: ΔG ‡ cat < … WebThe free energy, as defined by ΔG = ΔH − TΔS may be interpreted as representing the difference between the energy produced by the process, Δ H, and the energy lost to the surroundings, T Δ S. The difference between the energy produced and the energy lost is the energy available (or “free”) to do useful work by the process, Δ G.
