BIO 181 ASU EXAM 3 QUESTIONS AND ANSWERS 100% VERIFIED A statement that best describes the difference between potential and kinetic energy. - answerPotential energy is the energy associated with an object's position or state, while kinetic energy is the energy of motion. When an electron drops to an inner shell from an outer shell in an atom, what happens to its energy? - answerIt's potential energy decreases, and it's kinetic energy increases A statement that best described the primary difference between a chemical reaction and metabolism - answerChemical reactions are typically catabolic while metabolism includes both catabolic and anabolic processes For a chemical reaction to be spontaneous - answerThe change in Gibbs free energy must be negative When predicting whether a reaction is spontaneous, under certain conditions, which to thermodynamic parameters are typically combined to make this determination? - answerEnthalpy and entropy A statement that best describes the process of ATP hydrolysis in the context of an exergonic reaction? - answerATP hydrolysis releases energy as it breaks down ATP into ADP and inorganic phosphate (Pi) If the products of a chemical reaction have a higher enthalpy than the reactants, the reaction is - answerEndothermic and change in H is positive What primarily determines the direction of a chemical reaction? - answerThe change in Gibbs free energy What is the most common type of catalyst in living cells? - answerProteins (enzymes) How do enzymes increase the rate of chemical reactions? - answerBy lowering the activation energy required for the reaction to occur What is the transition state in a chemical reaction? - answerAn unstable, high energy state that molecules must pass through to convert into products
