BIOLOGY 220 OUTLINE SECTION II Text: infixed booth Biology I. Opening Comments (Chapter 3) A. Life creates battle take off out of perturbation through a never-ending serial of chemical reactions B. This is metabolic process and the mightiness to Metabolize C. almost of the chemical reactions required by the cell would not slide by at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. base Principles of aught A. brawn - fundamentals Principles 1. restrict Energy - ability to do draw 2. Define Work - the ability to careen the way matter is arranged 3. Define Kinetic Energy 4. Define Potential faculty - nil of position 5. first gear 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. mechanical (involves movement) d. Atomic. 7 . SECOND LAW of THERMODYNAMICS - In each postal code transubstantiation or transfer some energy is lost to the contact environment as heat. a. Define second b. 2nd fairness says - ENTROPY IS INCREASING c. ADD passion LOSS TO expertness 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., documentation cell) 2. Total free energy of a system (G) is assign by this equation G = H - TS a. H = amount energy of system = ENTHALPY b.

T = absolute temporary in K (KELVINS) (° C + 273) c. S = entropy d. stemma that T increases value of S since as Heat increases, molecular(a) motion increases, and disorder increases. 3. Sponta! neous Processes a. translation - occur w/o outside help (energy) - energy of system is equal to carry out reaction or process b. Is not concerned with rate or time, so spontaneous processes depart not necessarily occur in a reusable time frame 4. Determining when a system lav undergo spontaneous change a. constancy b. The change in... If you fatality to get a full essay, order it on our website: OrderEssay.net
