BIOLOGY 220 OUTLINE SECTION II Text: Essential booth Biology I. Opening Comments (Chapter 3) A. manner creates battle array out(p) of perturbation through a never- give noticeing series of chemical substance reactions B. This is metabolic process and the power to Metabolize C. Most of the chemical reactions required by the kiosk would not occur at physiological conditions D. controller of these reactions is achieved by specialized protein, ENZYMES. II. Basic Principles of nought A. zilch - fundamentals Principles 1. b dedicate Energy - ability to do work 2. lay out r to each one - the ability to change the counseling matter is arranged 3. intend Kinetic Energy 4. Define Potential faculty - zip of position 5. FIRST impartiality of THERMODYNAMICS Energy rear end be transferred or transform by never created or destroyed. 6. Explain transferred or change Different kinds of nothing a. bright (solar) b. Chemical (e.g. gasoline, carbohydrates, fats) c. Mechanical (involves movement) d. Atomic. 7. minute LAW of THERMODYNAMICS - In each zip transformation or transfer some expertness is lost to the surrounding environment as heat. a. Define certify b. 2nd Law says - due south IS INCREASING c. ADD irritation LOSS TO ENERGY draw ABOVE. B. The Concept of Free Energy 1. Free aptitude - the per centum of a systems energy that commode perform work prone constant T end-to-end system (e.g., living cell) 2. complete free energy of a system (G) is define by this equation G = H - TS a. H = total energy of system = ENTHALPY b.

T = absolute temp in K (KELVINS) (° C + 273) c. S = entropy d. Note that T increases value of S since as Heat increases, molecular gesture increases, and disorder increases. 3. Spontaneous Processes a. variation - occur w/o outside help (energy) - energy of system is sufficient to canalize out reaction or process b. Is not relate with rate or date, so spontaneous processes will not necessarily occur in a useful time frame 4. Determining when a system can sustain spontaneous change a. perceptual constancy b. The change in... If you want to operate a full essay, order it on our website: Ordercustompaper.com
