  2. Exergonic reaction - Wikipedia

    en.wikipedia.org/wiki/Exergonic_reaction

    The change of Gibbs free energy (ΔG) in an exergonic reaction (that takes place at constant pressure and temperature) is negative because energy is lost (2). In chemical thermodynamics, an exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy). [1]

  3. Activation energy - Wikipedia

    en.wikipedia.org/wiki/Activation_energy

    The activation energy (E a) of a reaction is measured in kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol). [2] Activation energy can be thought of as the magnitude of the potential barrier (sometimes called the energy barrier) separating minima of the potential energy surface pertaining to the initial and final thermodynamic ...

  4. Active site - Wikipedia

    en.wikipedia.org/wiki/Active_site

    Since bulk molecules can be excluded from the active site this energy output can be minimised. Next, the active site is designed to reorient the substrate to reduce the activation energy for the reaction to occur. The alignment of the substrate, after binding, is locked in a high energy state and can proceed to the next step.

  5. Activation - Wikipedia

    en.wikipedia.org/wiki/Activation

    The energy of activation [1] specifies the amount of free energy the reactants must possess (in addition to their rest energy) in order to initiate their conversion into corresponding products—that is, in order to reach the transition state for the reaction. The energy needed for activation can be quite small, and often it is provided by the ...

  6. Bioenergetics - Wikipedia

    en.wikipedia.org/wiki/Bioenergetics

    Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...

  7. Enzyme - Wikipedia

    en.wikipedia.org/wiki/Enzyme

    The rate of a reaction is dependent on the activation energy needed to form the transition state which then decays into products. Enzymes increase reaction rates by lowering the energy of the transition state. First, binding forms a low energy enzyme-substrate complex (ES).

  8. Reaction coordinate - Wikipedia

    en.wikipedia.org/wiki/Reaction_coordinate

    [2] An example is the complexation of two molecules. The distance between both of them is the collective variable, where the atomic positions are the individual variables x i and the reaction coordinate ξ would be the full path of association and dissociation. By applying a bias to the collective variables the simulation can be 'steered ...

    For example, when barium chloride (BaCl 2) and magnesium sulfate (MgSO 4) react, the SO 4 2− anion switches places with the 2Cl − anion, giving the compounds BaSO 4 and MgCl 2. Another example of a double displacement reaction is the reaction of lead(II) nitrate with potassium iodide to form lead(II) iodide and potassium nitrate: + +
