BIOL 1201 : Exam2
Document Summary
Burning of coal: change in g, delta g. Delta g=deltah-tdeltas: deltag-free energy change, deltah-enthalpy change, t-temperature(degrees kelvin, deltas-entropy change. Burning of coal: exergonic(exothermic, coal and oxygen, reactants, h20 and co2, products, heat is released, lump of coal on the table, why wont it burn, you have to add some energy to get the process started fig. Can be used for chemical or mechanical work. Heat is released: hyrdolysis, water added or water removed, water added, atp, standard free energy of hydrolysis is, -7. 3kcal/mol. 3 dimensional structure: an enzyme-catalyzed reaction generally doubles its rate for a 10 degree temp increase, you add heat, denaturation, thermopiles, bacteria-thermopiles exist at temp up to 132 deg c(grow at. 122 deg c: what sets the upper temp limit for life, the stability of biological molecules or liquid water, stab bio molecules. At high temp biological molecules, such as protein and dna, break down very rapidly.
