Presentation on theme: "Figure Number: 24-01b Title: Figure 24.1(b)"— Presentation transcript:

1 Figure Number: 24-01b Title: Figure 24.1(b) Caption: Reaction coordinate diagrams for catalyzed vs. uncatalyzed reaction. Notes: This figure shows the case where catalysis occurs because the catalyst lowers the energy of the transition state without changing the reaction mechanism.

2 Figure Number: 24-02 Title: Figure 24.2 Caption: Reaction coordinate diagrams for catalyzed vs. uncatalyzed reaction involving change of mechanism. Notes: This figure shows the case where catalysis occurs because the catalyst lowers the energy of the activated complex by changing the reaction mechanism.

3 Figure Number: 24-03a,b Title: Figure 24.3 Caption: Reaction coordinate diagrams for specific-acid-catalyzed and general-acid-catalyzed reactions. Notes: In specific-acid catalysis proton transfer leads to an intermediate preceding the rate-determining step. In general-acid catalysis proton transfer occurs during the rate-determining step

4 Figure Number: UNa,b Title: Lock-and-Key vs. Induced-Fit Models Caption: Schematic diagram illustrating the difference between the lock-and-key and induced-fit models of enzyme catalysis. Notes: In the lock-and-key model the enzyme active site does not change its shape to accommodate the substrate, whereas in the induced-fit model this does occur.

5 Figure Number: 24-06 Title: Top Half of Figure 24.6 Caption: Schematic diagram illustrating shapes and polarities of the binding pockets of trypsin, chymotrypsin, and elastase. Notes: Shapes and charge distributions in binding pockets explain why trypsin binds long basic (cationic) amino acids, chymotrypsin binds flat, nonpolar amino acids, and elastase binds only small amino acids.

6 Figure Number: 24-10 Title: Figure 24.10 Caption: pH-Rate Profile for Lysozyme. Notes: The optimum pH for enzyme activity is the pH midway between the pKa of a basic group which needs to be in its basic form to be active and an acidic group which needs to be in its acid form to be active.

7 Figure Number: 24-11 Title: Figure 24.11 Caption: Proposed mehanism of isomerization of d-glucose-6-phosphate to d-fructose-6-phosphate. Notes: This mechanism involves ring opening, three tautomerization steps which shift the carbonyl by one carbon, and ring closure.

8 Figure Number: Title: Table The pKa of Metal-Bound Water Caption: Notes:

9 Figure Number: Title: Table Relative Rates of an Intermolecular Reaction and Five Intramolecular Reactions Caption: Notes:
