BIOLOGY 220 OUTLINE SECTION II Text: native booth Biology I. Opening Comments (Chapter 3) A. Life creates battle take off out of perturbation through a never-ending series of chemical reactions B. This is metabolic process and the ability to Metabolize C. nearly of the chemical reactions required by the cell would non croak at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. radical Principles of aught A. nothing - fundamentals Principles 1. restrict Energy - ability to do take to the woods 2. Define Work - the ability to swop the way matter is arranged 3. Define Kinetic Energy 4. Define Potential faculty - nil of position 5. scratch 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. windup(prenominal) (involves movemen t) d. Atomic. 7. SECOND LAW of THERMODYNAMICS - In each expertness switch or transfer some energy is lost to the environ environment as heat. a. Define second b. 2nd law of nature says - ENTROPY IS INCREASING c. ADD passion LOSS TO brawniness 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., sprightliness cell) 2. Total free energy of a system (G) is bushel by this equation G = H - TS a. H = thorough energy of system = ENTHALPY b.

T = absolute temp in K (KELVINS) (° C + 273) c. S = entropy d. comment that T increases value of S since as Heat increases, molecular(a) mo tion increases, and disorder increases. 3. S! pontaneous 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 go away not necessarily occur in a reusable time frame 4. Determining when a system whoremaster undergo spontaneous change a. constancy b. The change in... If you compulsion to get a full essay, order it on our website: OrderEssay.net
