Section 6.1|Figs. 6.8-6.10, 6.17-6.19, 6.21-6.22 Saturday, December 01, 2007 2:20 PM Potential Energy - Stored Energy, EX: Chem Bonds, concentration gradiets, electric charge imbalance Kinetic Energy - Energy that does work Anabolism - Link simple molecules to form more complex molecules. EX: Synthesis of protein from amino acids. REQUIRE ENERGY INPUT and capture it in the chem bonds that form. Catabolism - Break down complex molecules into simpler ones and RELEASE ENERGY stored in chem bonds Laws of thermodynamics - Energy Neither Created nor destroyed, Second, when energy is converted from one form to another, some of that energy becomes unavailable to do work. None is 100% efficient Energonic Reaction - Reactions that require or consume free energy (+Delta G) Anabolic Reactions Exergonic Reaction - Reactions that release Fee Energy (-Delta G) Catabolic Reactions Enthalpy (H) - Total Energy Free Energy (G) - Usable energy that can do work Entropy (S) - Unusable energy Activation Energy - Energy barrier, amount of energy needed to start the reaction. Transition State - Higher free energies than either the reactants or products, their bonds can be stretched
