Step by step
Solved in 2 steps with 1 images
- Use the following graph to diagram the energetics of a chemicalreaction, with and without an enzyme. Be sure to position reactantsand products at appropriate points and to indicate the stages in thereaction and the energy levels.Briefly describe one of the mechanisms by which enzymes facilitate faster reaction rates in biological chemistryDraw a Gibbs free energy plot for a spontaneous reaction, and then draw how enzymes affect this plot
- Drag and drop the statements to the correct box: Enzymes DO: Decrease required activation energy Enzymes DON'T: Remain unchanged during the reaction Increase the reaction rate Energy Change the products made Activation energy (X+Y) reactants Change the reactants used Activation Energy A Activation energy (Y→X) products ΔΗ Reaction path Reaction without catalyst Reaction with catalyst Name two things we learned that can denature an enzyme:Use the following graph to diagram the energetics of a chemical reaction, with and without an enzyme. Be sure to position reactants and products at appropriate points and to indicate the stages in the reaction and the energy levels.Using an energy diagram, show why the lock-and-key model could lead to an inefficient enzyme mechanism. Hint: Remember that the distance to the transition state must be minimized for an enzyme to be an effective catalyst.
- Describe two catalytic mechanisms of enzymesExplain why enzymes are considered “biological catalysts” Use the following terms in the explanation: activation energy, lock and key model, substrate specificityEnzymes are important molecules in biochemistry that catalyze reactions. The energy diagram illustrates the difference between a catalyzed reaction and an uncatalyzed reaction. Label the energy diagram. Answer Bank activation energy reactants (substrate) free energy reaction progress transition state uncatalyzed reaction catalyzed reaction AG for reaction products
- Analyze the reaction below and identify the major class of enzyme that catalyzes the the given reaction:Enumerate the factors affecting enzyme catalysis and briefly explain each. And how does the structure of enzymes increase catalytic rate.PREDICT In the following reaction series, which enzyme(s) is/are most likely to have an allosteric site to which the end product E binds? (a) enzyme 1 (b) enzyme 2 (c) enzyme 3 (d) enzyme 4 (e) enzymes 3 and 4
