Time Which is correct regarding the concept of the lock-and-key as a theory of enzyme action: O a. Both D- and L-isomers of optically active substrates react ot the same rates. O b. The active site is flexible; the catalytic groups of the enzyme are brought complementary by the substrate. OC. The theory of lock-and-key is sufficient to explain the mechanism of enzyme catalysis. Od. The active site is rigid; the catalytic groups of the enzyme are complementary to the substrate. The oxidation of glucose to CO2 and H20 is highly exergonic: AG = 636 kcal/mole, This is spontaneous, but why is it very slow? a.

QUESTION/// Suppose two enzymes in different reaction pathways have the same substrate but have different level of affinities to it. At low [S], how will you differentiate the activities of the 2 enzymes? ///QUESTION
true or false 1. Conformational changes happen in an enzyme when the substrate binds to the active site. 2. Covalent bond stabilizes the binding of the substrate and the active site.
I am a bit confused about this PPT slide explanation. Why would a high energy transition state be favored when it requires more activation energy in an enzyme-substrate binding scenario?
9:34 AM You sent Help me with this one Select true if the statement is CORRECT and false if OTHERWISE 1. Enzymes are catalysts and increase the speed of a chemical reaction without themselves undergoing any permanent chemical change. 2. Catalysis is defined as the acceleration of a chemical reaction 3. if the amount of the enzyme is kept constant and the substrate concentration is then gradually increased, the reaction velocity will decrease. 4. In the Induced-fit Model, if a dissimilar substance which does not fit the site is present, the enzyme rejects it 5. The Michaelis constant Vo is defined as the substrate concentration at 1/2 the maximum velocity. 6. A prosthetic group - an organic substance which is dialyzable and thermostable which is firmly attached to the protein or apoenzyme portion. 7. The rate of an enzyme-catalyzed reaction increases as the temperature is raised beyond optimum temperature. 8. Enzymes can be classified by the kind of chemical…

an enzyme acts on a substrate X. The enzyme exists in four different forms, with different catalytic efficiencies. The table shows the kcatand KM values for each form of the enzyme. If the concentration of substrate X in a solution is 5 µM, which of the four forms of the enzyme is the most efficient? Form of Enzyme kcat (s-1) KM (µM) A 50 10 B 50 1 C 100 4 D 1000 100 a. Form A b. Form B c. Form D d. Form C
Describe the basics of enzyme structure and function. Be sure to address what makes enzymes specific, how active sites function and how substrates create an induced fit. Also, explain how enzymes can be inhibited by both a competitive inhibitor and a noncompetitive inhibitor.
