Three dipeptides are separated by electrophoresis at ph 5.8. if the dipeptides are Arg-trp, Asp-thr, and Val-met, describe the motion of each with respect tothe positive and negative electrodes in the electrophoresis apparatus.
Penicillin is hydrolyzed and thereby rendered inactive by penicillinase, an enzyme present in some resistant bacteria. The mass of this enzyme in Staphylococcus aureus is 29.6 kd. The amount of penicillin hydrolyzed in 1 minute in 10 ml solution containing 10–9 g of purified penicillinase was measured as a function of the concentration of penicillin. Assume that the concentration of penicillin does not change during the assay.
[Penicillin] µM Amount hydrolyzed (nanomoles)
1 0.11
3 0.25
5 0.34
10 0.45

A flat (not spherical) tissue engineered skin (thickness 3.9 mm) is attached to the bottom of a dish
and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The
diffusivity of oxygen in the skin is 3.2 E-9 m?/s, and according to experiments that you've performed,
you want to make sure that the concentration of oxygen in the device doesn't fall below 0.06
mol/m3. (Below that concentration harms the cells.)
The rate of oxygen consumption is -5 E-17 mol/[cell•s]. What is the maximum cellularity (in cells/mL,
three significant digits) that this tissue engineered skin can support?

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.
