- Substrates and reactive groups in an enzyme’s active site must be precisely aligned in order for a productive reaction to occur. Why, then, is some conformational flexibility also a requirement for catalysis?Explain how the position in the active site and function of the oxyanion hole of chymotrypsin supports the theory that enzymes preferentially bind the transition state of the reactions they catalyzeFor a lot of enzymes that work on fatty acids, the rate determining step is the release of the product from the active site. This means that the activation energy for product release is much higher than the free energy of catalysis. What enthalpic or entropic contributions would make the activation energy for product release so high and explain?
- Suggest a name for an enzyme that catalyzes each of the following reactions. Oxidation of nitrite Decarboxylation of citrate Reduction of oxalateIn a biochemical reaction that involves the substrate urea and the liver enzyme urease, decreasing the pH by one unit from its optimum value will _______ the rate of enzyme activity.Give an example of one enzyme that participates in both glycolysis and gluconeogenesis. Evaluate the structures of chemical reactants and products and the enthalpic and entropic contributions to Gibbs free energy change for the reaction. Explain how the enzyme is able to catalyze the reaction (either direction.)

True or False? The catalytic triad residues are all next to each other in the primary sequence of trypsin. True or False?We have encountered reactions similar to the oxidation, hydration, and oxidation reactions of fatty acid degradation earlier in our study of biochemistry. What other pathway employs this set of reactions?Compile a list of all the cofactors involved in adding or removing one-carbon groups in carbohydrate, lipid, and amino acid metabolism. Provide an example of a reaction that uses each cofactor.
- Consider an enzyme catalyzed reaction taking place in an aqueous solution. If the earlier process of folding the enzyme results in a large decrease in the entropy of the system, how would this impact the rate of the catalyzed reaction.You have a reaction that is very slow on its own, but is accelerated in the presence of an enzyme. Which of the listed effects would be brought about by an enzyme catalyzing this reaction? (Select all that apply) increased kcat increased Keq increased biochemical standard free energy change decreased activation energy_____________ allosteric effects of enzymes involve ligands that are different from substrate molecules.
