Starting with the Michaelis-Menten equation given on the first page, answer the following questions:
a) Write out the Michaelis-Menten model for an enzyme catalyzed reaction.
b) State at least two assumptions that must be made for enzymes that follow the Michaelis-Menten model.
Complete and balance an equation describing each of the above reactions. (Type your answer using the format CO2 for CO2, (NH4)2CO3 for (NH4)2CO3, [NH4]+ for NH4+, and [Ni(CN)4]2- for Ni(CN)42-. Use the lowest possible coefficients.)
A bottle containing 305 g of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
A 0.12M solution of a weak acid HA has pH = 2.49. What is the Ka of this acid.
Calculate the approximate volume of 0.02M KMnO4 (in the unit of mL) needed to titrate 0.17 g sodium oxalate.(Note: The KMnO4 solution will be added from a buret to a flask during titration.
Draw an arrow pushing mechanism for the formation of the acylium ion when acetic anhydride reacts with phosphoric acid.
Choose two functional groups and for each group find a household product that contains the group. Then explain the action of the product in terms of the intermolecular forces that these groups impart to the molecule.
Extraction procedures have shown that nitrogenase contains an iron-sulfur cluster, Fe4S4, where the atoms of each type are arranged alternatively at the corners of a cube.
A gas occupies 22.4 L at STP and 14.5 L at 100°C and 2.00 atm pressure. How many moles of gas did the system gain or lose?
A 15.00 mL sample of a 0.100 M solution of lead(II) nitrate is reacted with 10.00 mL of 0.170 M sodium chloride. How many grams of lead(II)
Consider the titration of 100.0 mL of 0.100 M HNO3 by 0.200 M NaOH.Calculate the pH after 34.5 mL of NaOH has been added.At what volume (in mL) of NaOH added does the pH of the resulting solution equal 7.00.
Nitrogen gas has a Henry's law constant k = 6.3 × 10-4 M/atm at 25°C. The "bends" in divers results from bubbles of N2(g) being rapidly released from body fluids when a diver ascends to the surface too quickly.
