40. Which of the following statements about transition state analog inhibitors are true? MARK ALL THAT APPLY. Group of answer choices Provide insight into catalytic mechanisms. Very potent and specific inhibitors. They have difficulty binding to the active site because they resemble the energetically unstable transition state of the substrate. Can be used as immunogens to generate catalytic antibodies.
1. Which of the following options is a viable way to increase the Vmax of an enzymatic reaction? Increase the amount of substrate present. Increase the amount of enzyme present. Decrease the temperature of the reaction. Decrease the Km of the enzyme.
5. Some enzymes can catalyze substrate reactions which result in the production of H* ions. If the batch reactor is not sufficiently buffered, this can lead to a change in pH. Because pH is an important factor in optimizing enzyme activity, the reaction velocity v can be altered during the reaction by the appearance of H* as a product. On a single graph, sketch a qualitative velocity profile (velocity vs. time) for the enzymatic breakdown of the substrate Auburn by the enzyme, WarEaglease for two conditions: A. An unbuffered solution that starts at pH 9. B. A well-buffered pH 9 solution. C. A well-buffered pH 7 solution.

Assume a high substrate concentration, so depletion of [S] does not cause the reaction to slow during the experiment. The relative activity of WarEaglease as a function…

7. In the ketone body pathway, both acetoacetate and B-hydroxy butyrate are produced and become additional fuel molecules for the organism. a. Define where these molecules are produced (both tissue type and location in the cell) and what tissue they "feed". b. Of these two molecules, which one is considered slightly better in delivering more energy to the target tissue? Why? c. How does acetone, another ketone body, participate in delivering fuel to target tissue? d. If acetoacetate decarboxylase enzyme was mutated and became inactive (zero enzyme activity), how would this affect the ketone pathway during these conditions: į. immediately after a meal, ii. under starvation conditions, iii. during unchecked (not being treated for) type-1 diabetes.
2C. A “pulse-chase" experiment using "C-labeled glucose can be carried out on a yeast extract that is maintained under strictly anaerobic conditions. The experiment consists of incubating a small amount of "C-labeled substrate (the pulse) with the yeast extract just long enough for each intermediate in the fermentation pathway to become labeled. The label is then “chased" through the pathway by the addition of excess unlabeled glucose. The chase effectively prevents any further entry of labeled glucose into the pathway. 2 ADP 2 ATP Glucose ---> CH3 2 NAD* 2 NADH 2 Pyruvate H H H-C-OH C=0 CH3 CH3 2 co, 2 Ethanol 2 Acetylaldehyde (1) If [1-"C]glucose (glucose labeled at C-1 with "C) is used as a substrate, will there be any "C in the product (ii) Lactic acid is the final fermentation product in vertebrates, while ethanol is the final fermentation product in yeast. Lactic acid can be converted back into glucose while ethanol can not be. In the space below, use a thermodynamic rationale to…
