- Explain how the Kirby-Bauer test works and what information it provides. Define minimum inhibitory concentration (MIC). Describe how the E-test works and what information it provides.Pyridoxal phosphate (PLP) is a coenzyme for the enzyme ornithine aminotransferase. The enzyme was purified from cells grow in PLP = deficient media as well as from cells grown in media that contained pyridoxal phosphate. The stability of the two different enzyme preparations was then measured by incubating the enzyme at 37°C for different lengths of time and then assaying for the amount of enzyme activity remaining. The following results were obtained. (a) Why does the amount of active enzyme decrease with the time of incubation? (b) Why does the amount of enzyme from the PLP deficient cells decline more rapidly?Given this, if you used 6g of vitamin Z powder to make 20 ml of solution, what is the % concentration of this solution? (I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria. One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution. Given that each bacterial…

Explain why these changes would need to be made. Describe one analytical (data visualization and interpretation) change that would have to be made to this assay if you wanted to observe the reaction above. Explain why this change would need to be made.State the principle that underlies the following biochemical tests: a. Voges-Proskauer testA purified protein sample was used in a reaction, resulting in an activity of 696.7 nmol min-1. The reaction volume was 145.0 µL and the final volume before loading the plate was 1,050 µL. The total reaction time was 4.25 min. The amount of protein used in the reaction was 4.270 µg. Calculate the specific activity of the sample (in nmol min-1 µg-1).
- Compounds I, II, and III are in the following biochemical pathway: precursor compound I enzyme A enzyme B compound II ► compound III enzyme Mutation a inactivates enzyme A, mutation b inactivates enzyme B, and mutation c inactivates enzyme C. Mutants, each having one of these defects, were tested on minimal medium to which compound I, II, or III was added. Fill in the results expected of these tests by placing a plus sign (+) for growth or a minus sign (-) for no growth in the table below. Minimal medium to which is added Strain with mutation Compound I Compound II Compound IIIThere are six classes of enzymes, namely oxidoreductases, transferases, hydrolases, lyases, isomerases and ligases. (i) (ii) Cell disruption is one of the steps performed during enzyme production. Explain the reason of performing cell disruption in enzyme production and provide THREE (3) enzyme extraction methods for this type of enzyme. Explain the principles of gel electrophoresis as one of the methods used for enzyme purification.Briefly comment on the differences of using a fixed-time assay versus a kinetic assay to measure enzyme activity. Is it reasonable to assume that the reaction velocity obtained by measuring the amount of product after 30 minutes in a fixed-time assay is directly proportional to absorbance? How could you determine whether this was the case? Word limit 180 words including citation and reference
