Question
1. (2 pts) Which one of the following statements is TRUE? A. In an anabolic process, complex precursors are converted to simpler products. B. Free energy is available to do work at constant temperature and pressure. C. Metabolism is defined as the breakdown of complex molecules to release energy. D. In any chemical process, total entropy of products must equal that of the reactants. E. Catabolic processes require an overall input of energy. 2. (3 pts) The Gibbs free energy equation is: AG AH-TAS A. If the value of AG for a given reaction is a positive number, is the reaction exergonic B. Under these circumstances, will the reaction tend to proceed spontaneously as C. If the entropy change of the reaction decreases under specific conditions while or endergonic? written? Answer "yes" or "no." other parameters remain constant, will ?G increase or decrease?Explanation / Answer
Ans 1 A: FALSE.
Anabolic processes build and catabolic processes breakdown. Catabolic processes convert complex substances to simpler ones.
Ans 1 B: TRUE.
Free energy is useful work energy - Gibbs free energy - which is available for work at constant temprature and pressure.
Ans 1 C: FALSE.
Process of breakdown of complex particles into simpler ones is called catabolism.
Ans 1 D: FALSE.
Entropy can increase or decrease in a chemical reaction. For example, in condensation entropy decreases while in sublimation entropy increases. Chemical reactions involving dissociation are associated with increase in entropy and those involving association (as in dimerization) will decrease entropy.
Ans 1 E: FALSE.
When catabolic processes breakdown complex substances energy is released. Anabolic process which build complex substances from simpler ones require energy.
