Biol 002 Lecture 3 study outline Textbook Reading: Chapter 8 (pages 144-145,147, 154-156) Chapter 9 (p. 160-163, 172-173) Objectives: Free energy predicts the directions of reactions. How is ATP used in energy coupling? What is the role of enzymes in energy coupling? What is energy metabolism? What are oxidation and reduction? What is glucose respiration? (a first look) I. Self-review of enzymes What are the properties and principles of enzymes? II. Energy and reactions (textbook pages 144, 145, 147) A. Chemical reactions tend toward equilibrium: Does that mean all reactions stop at equilibrium? B. Different ways to describe direction of the reaction not at equilibrium: (favorable, spontaneous, exergonic vs. unfavorable, nonspontaneous, endergonic) C. Look at "free" energy (G) profile (Fig. 8.6) for an explanation of reaction direction: Do reactions go toward higher or lower free energy? D.
