Unformatted text preview: Biochemistry Exam #2 Ch6 Notes: 6.1 • Enzymes o Increase the rate of a reaction by 10^6 or more, up to 10^20 o They do not alter the equilibrium or change Delta G of a reaction but increases the RATE at which the equilibrium is reached o Nonenzymes catalysts increase rate to 10^2 to 10^4 6.2 • Kinetics v Thermodynamics o Kinetics- the rate of a reaction, how fast it occurs o Thermodynamics- weather it can occur without the input of addition energy, if its spontaneous o Spontaneous- in thermodynamics, characteristic of a reaction or process that takes place without outside intervention o Thermodynamics is concerned with the difference between the energies of the reactants vs the energies of the products, Standard free energy change. o Standard free energy change (delta G)- the difference between the energies of the reactants (initial state) and the energies of the products (final state) of a rxn, giving the E change. The Standard free engery change for the reaction (Delta G) remains unchanged when a catalyst is added, but the activation energy (Delta G++) is lowered Thermodynamically favorable- if there is a decrease in the free energy going from reactants to products, energy is released ( exergonic- energy releasing) •...
