Enzyme Investigation An enzyme was isolated from digestive juices taken from the small intestine. An experiment was set up to test the ability of the enzyme to break down protein. Two test tubes, labeled A and B, were placed in a hot water bath at 37°C, human body temperature. Test tube A contained only protein and test tube B contained protein and the enzyme. The chart below shows the set-up. Test Tube Contents A protein В protein, enzyme After two hours, the contents of both test tubes were analyzed. Test tube A showed only the presence of protein. Test tube B showed the presence of the end products of protein digestion, indicating the enzyme had successfully broken down the protein. 17. Explain the importance of temperature in the functioning of enzymes. 18. Identify the end products of protein digestion that made up the contents of test tube B after the two hours. 19. In the digestive system many large molecules, such as proteins, are broken down into much smaller molecules. State what happens to these smaller molecules following digestion.

A student performed an invertase activity assay on samples from a purification. All reactions occurred in a reaction volume of 100 µL and lasted 3.1 minutes. For each reaction, 8.50 µL enzyme was mixed with 50.0 mM sucrose in 10.0 mM acetate pH 4.8. Then 400 µL of DNS was added, the samples were heated to 90 °C for 5 minutes, and 300 µL of 50.0 mM acetate pH 4.8 was added before loading a 96 well plate in triplicate. Samples were measured at 540 nm using a path length of 0.730 cm. The fraction with the highest activity had A540 of 0.743. The standard of 14.00 mM hydrolyzed sucrose had A540 of 1.087 (the concentration given is of the 100 µL sample). The no-enzyme control had A540 of 0.139. Calculate the activity of the fraction (in nmol min-1).
200 ml of a 2% protein solution are available, containing an enzyme to be purified. Half of the sample is subjected to method A, consisting of fractionated precipitations, and 5 ml of final solution are obtained, with a protein concentration equal to 5 mg / ml and enzymatic activity equal to 2000 U / ml. The other half is subjected to method B, consisting of ion exchange chromatography, and a final solution of 10 ml is obtained, with a protein richness equal to 10 mg / ml, and with an enzymatic activity equal to 2000 U / ml. You want to know: a) Which of the methods has provided the purest enzyme. b) By which of the methods has the greatest amount of protein been obtained.
A 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).
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…
A student purified a protein, resulting in a fraction with a volume of 240 µL. The sample has a corrected A280 of 0.234, and the blank corrected A280 was 0.069. (Both values were measured with a path length of 1.00 cm.) The student then added 6.00 µL of the sample to a reaction tube. Calculate the mass of protein in the reaction (in µg).
