- RECALL Is there a connection between the free-energy change for a reaction and its equilibrium constant? If there is a connection, what is it?arrow_forwardRECALL What is a suicide substrate? Why are they important?arrow_forwardRECALL Why is it necessary to define a modified standard state for biochemical applications of thermodynamics?arrow_forward
- REFLECT AND APPLY In Section 2-4, we said that at the equivalence point of a titration of acetic acid, essentially all the acid has been converted to acetate ion. Why do we not say that all the acetic acid has been converted to acetate ion?arrow_forwardRECALL Show graphically how the reaction velocity depends on the enzyme concentration. Can a reaction be saturated with enzyme?arrow_forwardREFLECT AND APPLY Would nature rely on the same enzyme to catalyze a reaction either way (forward or backward) if the DG were 0.8kcalmol1? If it were 5.3kcalmol1?arrow_forward
- RECALL How can you tell if the standard Gibbs free energy given for a reaction is for chemical standard states or biological standard states?arrow_forwardREFLECT AND APPLY List two classes of compounds derived from arachidonic acid. Suggest some reasons for the amount of biomedical research devoted to these compounds.arrow_forwardREFLECT AND APPLY Why is it somewhat misleading to study bio- chemical pathways separately?arrow_forward
- REFLECT AND APPLY Other things being equal, what is a potential disadvantage of an enzyme having a very high affinity for its substrate?arrow_forwardRECALL Define the term reducing sugar.arrow_forwardREFLECT AND APPLY Noncompetitive inhibition is a limiting case in which the effect of binding inhibitor has no effect on the affinity for the substrate and vice versa. Suggest what a LineweaverBurk plot would look like for an inhibitor that had a reaction scheme similar to that on page 159 (noncompetitive inhibition reaction), but where binding inhibitor lowered the affinity of EI for the substrate.arrow_forward
