A new medical test has been designed to detect the presence of
the mysterious Brainlesserian disease. Among those who have the
disease, the probability that the disease will be detected by the
new test is 0.78. However, the probability that the test will
erroneously indicate the presence of the disease in those who do
not actually have it is 0.02. It is estimated that 19 % of the
population who take this test have the disease.

A medical test has been designed to detect the presence of a
certain disease. Among people who have the disease, the probability
that the disease will be detected by the test is 0.93. However, the
probability that the test will erroneously indicate the presence of
the disease in those who do not actually have it is 0.03. It is
estimated that 3% of the population who take this test have the
disease. (Round your answers to three decimal places.)

Medical testing: enzyme linked immunosorbent assay
(ELISA) test for presence of antigen or antibody
EXPERIMENTAL PROTOCOL
In this laboratory, you will test seven different patients using
a direct ELISA. We have access to serum samples from the main
characters of the TV show The Big Bang Theory. You will test each
of them for the presence of ZIKA virus and HIV, as well as perform
a pregnancy test, using known antigens/antibodies for those
diseases/test. Students will work in pairs. Serum...

Determine the Vmax and the Km of the enzyme in the absence and
presence of each inhibitor. Calculate the KI for each inhibitor.
Are the inhibitors all the same? Which is the best inhibitor and
why? What is the catalytic efficiency and turnover number of the
enzyme knowing that during the experiments its concentration was 2
nM? What happens to the catalytic efficiency and turnover number of
the enzyme in the presence of each of the inhibitor?
The following velocity...

The enzyme is studied in the presence of a different inhibitor
(inhibitor B). In this case, two different concentrations of
inhibitor are used. Data are as follows:
a) Determine the apparent Vmax at each inhibitor
concentration.
b) Determine the apparent KM at each inhibitor
concentration.
c) Estimate KI from these data. [Hint: Calculate the
KI at 3 mM and at 5 mM; and then take the average of the
two KI values.]

A substrate is decomposed in the presence of an enzyme according
to the Michaelis-Menten equation
with the following kinetic parameters:
Km = 20 g/L
Vmax = 12.0 g/L-min
(a) Determine the concentration of substrate after leaving the
second reactor in a two-reactor series of
20-liter CSTRs. The flow rate is 2.00 L/min. The inlet substrate
concentration is 40 g/L. The
enzyme concentration in the two reactors is maintained at the same
value all of the time.
(b) Determine the conversion...
