AP Biology Chapter 8 Study Bullets Define: Catabolism (increase entropy of a cell) (supply energy for the cell) Anabolism (decrease entropy of a cell) Endergonic ( positive delta G) (Delta S?) (Delta H) Exergonic ( negative delta G) (Delta S?) (Delta H?) Enthalpy ( heat content) Define The First Law of Thermodynamics (Organism obtains energy from its environment) Define The Second Law of Thermodynamics (Cells require a constant input of energy) Chemical Equilibrium = No Work An Example: A chemical reaction in which reactants and products are not being used. Why doesn’t a cell use heat to perform work? When work is done by the cell heat is lost to the environment. Know the diagram for ATP (Phosphorylated Intermediate) page 151 Define Activation Energy-thermodynamic barrier Know the function of Enzymes ( Do not change Delta G) Define Active Site, Co-factors,Co-enzymes, Non-competitive Inhibitor, Feedback Inhibition, Enzyme Cooperativity, Allosteric Inhibitor Which level of enzymes are affected by intense heat? Pri,Sec,Tert,Quat How do Enzymes Lower Activation Energy?
