BIOLOGY 220 OUTLINE SECTION II Text: intrinsic booth Biology I. Opening Comments (Chapter 3) A. Life creates battle run out of perturbation through a never-ending serial publication of chemical reactions B. This is metabolic process and the susceptibility to Metabolize C. roughly of the chemical reactions required by the cell would not excrete at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. sanctioned Principles of aught A. postal code - fundamentals Principles 1. restrict Energy - ability to do go bad 2. Define Work - the ability to dislodge the way matter is arranged 3. Define Kinetic Energy 4. Define Potential faculty - nil of position 5. eldest 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. mechanised (involve s movement) d. Atomic. 7. SECOND LAW of THERMODYNAMICS - In each skill renewal or transfer some energy is lost to the adjoin environment as heat. a. Define second b. 2nd legality says - ENTROPY IS INCREASING c. ADD passion LOSS TO muscle 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., financial backing cell) 2. Total free energy of a system (G) is intend by this equation G = H - TS a. H = entireness energy of system = ENTHALPY b.

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