You are trying to come up with a drug to inhibit the activity of an enzyme thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed a competitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Km of the enzyme was found to be 1.5 x 10-5 M. What is the Ki of the inhibitor?

You are trying to come up with a drug to inhibit the activity of an enzyme thought to have a role in liver disease. In the laboratory the enzyme was shown to have a Km of 1.0 x 10-6 M and Vmax of 0.1 micromoles/min.mg measured at room temperature. You developed an uncompetitive inhibitor. In the presence of 5.0 x 10-5 M inhibitor, the apparent Vmax was determined to be 0.02 micromoles/min.mg. What is the Ki of the inhibitor?

Draw the nullclines and find equilibria of the following extensions of the basic disease model. Find the nullclines and equilibria of this model when α = 2.0, µ = 1.0, and k = 4.0.
Suppose that you have an enzyme concentration at the molarity calculated in question 2 and the product that you monitor has a value of ε = 6200 M1 cm1. You ran eight reactions and found the following: Reaction # [substrate] (μM) Slope (Abs/min) 1 0 0.000 2 10 0.163 3 20 0.288 4 60 0.586 5 100 0.740 6 200 0.920 7 500 1.078 8 1000 1.143 M=4.45x10-M Calculate the values of Kcat and KM for the reaction (remember to include units).

The Michaelis-Menten equation is often used to describe the kinetic characteristics of an enzyme-catalyzed reaction. Vmax [S] U = Km + [S] where v is the velocity, or rate, Vmax is the maximum velocity, Km is the Michaelis-Menten constant, and [S] is the substrate concentration. A graph of the Michaelis-Menten equation is a plot of a reaction's initial velocity (vo) at different substrate concentrations ([S]). First, move the line labeled Vmax to a position that represents the maximum velocity of the enzyme. 300 V Next, move the line labeled 1/2 Vmax to its correct position. max 275 Then, move the line labeled Km to its correct position. 250 225 200 175 Michaelis–Menten curve 150 K a 125 m 100 1/2 V 75 max 50 25 10 20 30 40 50 60 70 80 90 100 [S] (µM) Incorrect Estimate the values for Vmax and Km.

The enzyme urease increases the rate of urea hydrolysis at pH 8.0 and 20 °C by a factor of 1014. Suppose that a given quantity of urease can completely hydrolyze a given quantity of urea in 19 minutes at pH 8.0 and 20 °C. How long would it take for this amount of urea to be hydrolyzed in the absence of urease at the same temperature and pH in sterile conditions? Include two significant figures in your answer. timeuncatalyzed years * TOOLS x10
You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.
