Suppose an enzyme has Km = 0.1mM and kcat = 10^3 s-1, and you perform an experiment in which [E]tot = 10-7M. Suppose that adding 0.1 µM of an inhibitor results in a Kmeff= 0.5 mM, and has no effect on kcat. Determine the substrate concentation that would be necessary to achieve a reaction velocity v of 5*10^-5Ms-1

1.For the diprotic weak acid H2A, Ka1 = 2.5 × 10-6 and Ka2 = 7.5 × 10-9. What is the pH of a 0.0400 M solution of H2A? What are the equilibrium concentrations of H2A and A2– in this solution? 2.HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.026 M in NaClO at 25 °C? 3.NH3 is a weak...

10. Continuing with the same population in Question 7, let us consider the case where we picked a sample of size 14. (Do not worry about the fact that it is stupid to have a sample of size 14 when the population has only 4 people in it.) What is the standard error (deviation) of the sampling distribution of the mean? 11. You need to clean out a fish tank, so you get a small bowl to take out all...
