Attempt 4 - Bacteria and other microbes can be used to clean up an oil spill by breaking down oil into carbon dioxide and water. Two samples isolated from the Deepwater Horizon leak in the Gulf of Mexico were labeled A and B. The DNA of each was isolated and the percent thymine measured in each sample Sample A contains...

Imagine these two products are dissolved in CH2Cl2. The solution
is treated with 2-propanol/HCl until pH is approximately 7,
resulting in the formation of crystals. The crystals are isolated
using vacuum filtration. The sequence of actions described above
results in the separation of the two products A and B. Why? How?
Write a concise discussion.

An enzyme that degrades pheromone is isolated from the sensory hairs of the silk moth, Antheraea polyphemus. The kinetics of the reaction are studied at pH 7.2 using a fixed enzyme concentration and temperatures of 10 C to 40 C. The following table lists results for reaction velocity as a function of substrate concentration. (a) Determine vmax and km at...
