departure of the 5؅ leaving group is the rate-limiting step for the natural all-RNA substrate (R11O) in both nonen-zymatic and hammerhead ribozyme-catalyzed reactions; the energy diagrams for these reactions were provided in our pre-vious publication. Note that the activation energy between reactant and the intermediate (step 1, ΔG ‡ 1) is greater than the activation energy between the intermediate and the products (step 2, ΔG ‡ 2). Thus it can be said that step 1 is the rate-limiting step of the reaction, which is the highest energy barrier that must be overcome. Graph 3 ATP is synthesized primarily by a two-step process consisting of an electron-transport chain and a proton gradient. Coupled reactions are frequently used in the body to drive important biochemical processes. Separate chemical reactions may be added together to form a net reaction. Step 1: Determine the magnitude of the rate constant, k. Unlike a first order reaction, the rate constant for a second order process depends on and the initial concentration of a reactant. Activation Energy Arrhenius: Molecules must posses a minimum amount of energy to react.
