1.How would you make 1 mL of a 1 to 25 dilution of yeast crude extract?
2. Enzyme activity measures:
A)The number of polypeptide molecules
B)The number of substrate molecule
C)The energy used in the reaction
D)The rate at which substrate is processed by the enzyme

1.How would you make 1 mL of a 1 to 25 dilution of yeast crude extract?...
How would you make 1 mL of a 1 to 25 dilution of yeast crude extract? Be specific.
How would you make 120 mL of a 1 to 25 dilution of a yeast extract? I'm really not understanding this process so steps/explanations would be nice. Thanks.
1. You want to prepare a 1:50 dilution of your protein extract in a total volume of 1000 uL. You will need ___ uL of protein extract and ___ uL of water. 2. You are provided with a solution of BSA that is 100 ug/mL and make a 10-2 dilution? What is the resulting concentration of the DILUTED BSA? 3. Which of the following statements about enzymes is true? Select one: a. Enzymes increase the rate of a chemical reaction...
A crude cell extract containing 2 g.L -1 of protein was assayed for enzyme activity using an excess of substrate. It was found that 5 ml of the solution converted 25 µmoles of substrate to product over a period of 2 minutes. (i) Calculate the specific activity of the enzyme. The crude extract was subjected to anion exchange chromatography followed by gel filtration. After anion exchange the specific activity had risen to 226 µmoles.min-1 .mg-1 , and after gel filtration...
You were given a 25 mg/mL stock of enzyme A, how would you use a serial dilution series to make a 5 ug/mL stock? What is the final dilution factor?
Multi-part question according to lab textbook: A student is analyzing crude cellular extract for protein content. Crude cellular extract is simply the cellular contents obtained by lysing (breaking open) cells. Which method (A280 or biuret) would be the most appropriate method for determining protein concentration and why? A student has purified a blood protein with an extinction coefficient of 1.86 (mg cm/mL^-1) which the student compares to another blood protein which has an extinction coefficient of 0.72 (mg cm/mL^-1). Which...
you’re asked to make 380 ml of a 1/20 dilution. how many ml of diluent will be used
Explain how you would make a 1/1000 dilution of a bacterial suspension if you only had 3 ml aliquots of BHI broth (diluent) available. What size pipetman will you need to use to make this dilution?
Show how you would make up a 10-5 dilution, given 1 ml pipets and 99ml water blanks. Your original samples is undiluted milk.
You have 25 ml of a yeast culture that contains 8 x 10^9 cells/ml. How would you dilute this culture so that you have exactly 5 ml of culture that contains 2 x 10^2 cells/ml?
