3 How Does Destabilization of ES Affect Enzyme Catalysis?
Which of the following statements about inhibition is true? a. Allosteric inhibitors and allosteric activators are competitive for a given enzyme. b. If an inhibitor binds the active site, it is considered noncompetitive. c. If an inhibitor binds to a site other than the active site, this competitive inhibition. d. A noncompetitive inhibitor is believed to change the shape of the enzyme, making its active site inoperable. e. Competitive inhibition is usually not reversible.
In an enzymatic reaction: a. the enzyme leaves the reaction chemically unchanged. b. if the enzyme molecules approach maximal rate, and the substrate is continually increased, the rate of the reaction does not reach saturation. c. in the stomach, enzymes would have an optimal activity at a neutral pH. d. increasing temperature above the optimal value slows the reaction rate. e. the least important level of organization for an enzyme is its tertiary structure.
Which of the following methods is not used by enzymes to increase the rate of reactions? a. covalent bonding with the substrate at their active site b. bringing reacting molecules into close prosimity c. orienting reactants into positions to favor transition states d. changing charges on reactants to hasten their reactivity e. increasing fit of enzyme and substrate that reduces the energy of activation
Which of the following analogies best describes the induced-fit model of enzyme-substrate binding? a hug between two people a key fitting into a lock a square peg fitting through the square bole and a round peg fitting through the round hole of a children’s toy the fitting together of two jigsaw puzzle pieces
1. There are two major categories of enzyme, inhibition, name, and describe them. 1a. Reverse inhibition can be overcome to allow the enzyme to resume is Catley activities. Describe how reversible inhibition can occur and how it can be over come.
3. What is the marker for the enzyme’s optimum condition?
5) Consider the hypothetical biochemical pathway shown below. Assume that each letter (A, B, C, etc) represents a molecule and each number over an arrow (1, 2, 3, etc) represents an enzyme that catalyzes that reaction (so enzyme 2 catalyzes the conversion of B to C). Indicate all the probable feedback inhibition interactions that would be expected to regulate the activity of enzymes in this pathway. please indicate each interaction in the format example: "X will inhibit enzyme 27".
1. Demonstrate your understanding whether carrier-free biocatalysts should or should not be considered as good biocatalysts. You discussion must be in detail and related to biocatalysis. You can provide detail explanation or provide example. 2. Compare and contrast the following pairs of terms. Relate their similarities and differences to applications in biocatalysis. Zymonomas sp. and Saccharomyces sp.
1. Can you describe how electrostatic and steric considerations may lead to preferential stabilization of the transition state at an enzyme active site? 2. What factors are involved in “transition-state complementarity”?
#1 Specify the role each of the following amino acids play within the crystal structure and/or active site for Be as specific as possible, with pictures (and mechanistic arrows) as necessary. His11 Arg140 Glu89 Trp68 #2 Provide a step-wise mechanism for the reaction Bisphosphoglycerate mutase catalyzes, using the amino acids responsible for aiding in catalysis. You do not need to add surrounding amino acids that aid in substrate specificity. (drawn out)
5. a) Why would an enzyme that is effective with one reaction have no effect on another reaction?
