The rate of a simple enzyme reaction is given by the standard Michaelis–Menten equation:
rate = Vmax [s]/([s] + KM)
if the Vmax of an enzyme is 100 μmole/sec and the KM is 1 mM, at what substrate concentration is the rate 50 μmole/sec? Plot a graph of rate versus substrate (s) concentration for [s] = 0 to 10 mM. Convert this to a plot of 1/rate versus 1/[s]. Why is the latter plot a straight line?
Fluorine-18 (F-18) is a commonly used radionuclide for PET scans. The
half-life of F-18 is 110 min. F-18 is used to label the glucose molecules to form the
radiotracer called Fludeoxyglucose (FDG). Only consider the physical half-life. Initially,
a 5 ml FDG solution was prepared at a concentration of 4 mCi/ml. After 220 min, the
FDG solution was all administrated to a patient. Calculate the following questions.
Show steps to earn full points.
(1) The initial radioactivity of the solution Ag.
(ii) The decay constant of F-18 2.
(iii) The actual radioactivity that the patient received Ap.
Show that the activity of the 14C in 1.00 g of 12C found in living tissue is 0.250 Bq.
