- REFLECT AND APPLY Why are proteins more effective catalysts than RNA molecules?arrow_forwardRECALL What is the Holliday Model?arrow_forwardREFLECT AND APPLY Nucleic acids are polymers of just four different monomers in a linear arrangement. How many different sequences are available if one makes a polymer with only 40 monomers? How does this number compare with Avogadros number?arrow_forward
- RECALL What quality of zwitterions makes them desirable buffers?arrow_forwardRECALL Draw an example of a compound that would serve as a cation exchanger. Draw one for an anion exchanger.arrow_forwardRECALL Why is it necessary to define a modified standard state for biochemical applications of thermodynamics?arrow_forward
- REFLECT AND APPLLY Show that the reaction Glucose2Glycer-aldehyde-3- phosphate is slightly endergonic (G'52.2kJmol1=0.53kcalmol1); that is, it is not too far from equilibrium. Use the data in Table 17.1.arrow_forwardREFLECT 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 How can you tell if the standard Gibbs free energy given for a reaction is for chemical standard states or biological standard states?arrow_forward
