A pesticide inhibits the activity of a particular enzyme, which can therefore be used to assay for the presence of the pesticide in an unknown sample. a) In the laboratory, the initial rate data shown in the table below were obtained. What type of inhibitor (competitive, uncompetitive, non-competitive) is the pesticide? Determine the values of Vmax, KM, and KI. v, M/min x 106 S, M No inhibitor 10-5 M inhibitor 3.3 x 10-4 56 37 5.0 x 10-4 71 47 6.7 x 10-4 88 61 1.65 x 10-3 129 103 2.21 x 10-3 149 125
The final temperature of the uranium and deuterium oxide mixture is 28.5C. Given the densities of uranium (19.05 g/cm3) and deuterium oxide (1.11 g/mL), what is the edge length of the cube of uranium?
Heat is transferred to the vessel until one phase just disappears, and a single phase remains. Which phase (liquid or vapor) remains, and what are its temperature and pressure? How much heat is transferred in the process?
If the higher-pressure steam expands in a turbine of 78% efficiency and the lowerpressure steam is compressed in a machine of 75% efficiency. Make a thermodynamic analysis of this process.
The ideal-gas heat capacities of ethylene and nitrogen are 43 J/mol K and 29 J/mol K, respectively, and may be assumed independent of temperature.
How many possible plaintexts will the receiver find at the end of the decryption process?
A 12.6-g sample of acetylene, C2H2, produced a temperature increase of 16.9C in the same calorimeter. What is the energy of combustion of acetylene (in kJ/mol)?
Question - 22 25 tons of caustic solution having 10 % concentration was fed to an evaporator . the concentrated liquor leaving the evaporator contains 50% NaOH , 2 % Nacl and 48 % H2O .
The band gap of indium gallium arsenide varies based on the concentration of gallium in the material. A sample of indium gallium arsenide absorbs light with a wavelength less than 1.37 microns. What is the band gap of the indium gallium arsenide samp..
Calculate the mass of methane that must be burned to provide enough heat to convert 363.0 g of water at 43.0°C into steam at 117.0°C. (Assume that the H2O produced in the combustion reaction is steam rather than liquid water.)
As a system increases in volume, it absorbs 55.0 J of energy in the form of heat from the surroundings. The piston is working against a pressure of 0.502 atm. The final volume of the system is 57.7 L. What was the initial volume of the system if t..
Before developing the dead-weight gauge, he worked in a mine shaft, and used a mercury manometer for measurements of pressure to more than 400 bar. Estimate the height of manometer required.
