BIOLOGY 220 OUTLINE SECTION II Text: all-important(a) booth Biology I. Opening Comments (Chapter 3) A. Life creates battle multitude out of perturbation through a never-ending serial publication of chemical reactions B. This is metabolic process and the muscle to Metabolize C. nearly of the chemical reactions required by the cell would non pass by at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. basal Principles of aught A. muscularity - fundamentals Principles 1. restrict Energy - ability to do subject field 2. Define Work - the ability to diversify the way matter is arranged 3. Define Kinetic Energy 4. Define Potential faculty - nil of position 5. first base 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. machin elike (involves movement) d. Atomic. 7. SECOND LAW of THERMODYNAMICS - In each energy variation or transfer some energy is lost to the adjoin environment as heat. a. Define second b. 2nd police says - ENTROPY IS INCREASING c. ADD passion LOSS TO competency 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., life-time cell) 2. Total free energy of a system (G) is set by this equation G = H - TS a. H = hit energy of system = ENTHALPY b.

T = absolute temp in K (KELVINS) (° C + 273) c. S = entropy d. placard that T increases value of S since as Heat increases, molecul! ar motion increases, and disorder increases. 3. Spontaneous Processes a. translation - occur w/o outside help (energy) - energy of system is fitted to carry out reaction or process b. Is not concerned with rate or time, so spontaneous processes allow not necessarily occur in a usable time frame 4. Determining when a system tush undergo spontaneous change a. constancy b. The change in... If you fatality to get a full essay, order it on our website: BestEssayCheap.com
