Anabolic - Small molecules assemble into large ones. ENERGY IS REQUIRED , Catabolic - Large molecules break down into small ones. ENERGY IS RELEASE, Chemical energy - call the potential energy type that exists within chemical bonds that releases when those bonds break, Free energy or Gibbs free energy - A measurement used to quantify energy transfers, Exergonic reactions - Negative G reaction in which free energy is exiting the system., Endergonic reactions - If a chemical reaction requires an energy input rather than releasing energy, then the ∆G for that reaction will be a positive value. In this case, the products have more free energy than the reactants., Activation energy - small amount of energy input necessary for all chemical reactions to occur, Transition state - small energy input is required to achieve this contorted state. This contorted state is the _____________, 1st law of Thermodynamics - Energy cannot be created or destroyed, 2nd law of Thermodynamics - For a spontaneous process, the entropy increases., Heat energy - energy that transfers from one system to another that is not doing work., Entropy - Scientists refer to the measure of randomness or disorder within a system as, Metabolism - Refers to all chemical reactions of a cell or organism, Enthalpy - A system's total energy,
