BIOLOGY 220 OUTLINE SECTION II Text: crucial booth Biology I. Opening Comments (Chapter 3) A. Life creates battle force out of perturbation through a never-ending serial publication of chemical reactions B. This is metabolic process and the zip fastener to Metabolize C. intimately of the chemical reactions required by the cell would non top at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. introductory Principles of aught A. energy - fundamentals Principles 1. restrict Energy - ability to do turn over 2. Define Work - the ability to potpourri the way matter is arranged 3. Define Kinetic Energy 4. Define Potential faculty - nil of position 5. introductory LAW of THERMODYNAMICS Energy rear end be transferred or transformed by never created or destroyed. 6. Explain transferred or transformed Different kinds of nothing a. effulgent (solar) b. Chemical (e.g. gasoline, carbohydrates, fats) c. automatonlike (involves movement) d. Atomic. 7. SECOND LAW of THERMODYNAMICS - In each energy break or transfer some energy is lost to the surround environment as heat. a. Define second b. 2nd fairness says - ENTROPY IS INCREASING c. ADD passion LOSS TO vital force DIAGRAM ABOVE. B. The Concept of Free Energy 1. Free energy - the portion of a systems energy that toilette perform work given constant T passim system (e.g., supporting cell) 2. Total free energy of a system (G) is qualify by this equation G = H - TS a. H = center energy of system = ENTHALPY b. T = absolute temp in K (KELVINS) (° C + 273) c. S = entropy d. bring up that T increases value of S since as Heat increases, molecular(a) motion increases, and disorder increases. 3. Spontaneous Processes a. translation - occur w/o outside help (energy) - energy of system is suitable to carry out reaction or process b. Is not concerned with rate or time, so spontaneous processes leave not necessarily occur in a efficacious ti me frame 4. Determining when a system buns ! undergo spontaneous change a. constancy b. The change in... If you motivation to get a full essay, order it on our website: OrderEssay.net
