Carbon monoxide binds strongly to the Fe2+ion of the heme group of protein myoglobin. Suppose you have at your disposal a supply of myoglobin, a suitable buffer in which to suspend the protein,12C16O,13C16O,12C18O,13C18O, and an infrared spectrometer. Assuming that (i) the atom that binds to the heme group is immobilized, (ii) the protein is infinitely more massive than either the C or O and(iii) atom isotopic substitution does not affect the force constant of the CO bond, describe a set of experiments that: (a) proves which atom C or O binds to the heme group of myoglobin, and (b)allows for the determination of the CO force constant for myoglobin-bound carbon monoxide. In your description of the experiments, tell what data you would collect and how you would interpret the data
what is the total pressure in the reaction flask at the end of the reaction? What are the partial pressures of the gases in the flask? 4A(g) + 6B(g) ? 2A2B3(g)
Describe the Bohr effect in oxygen binding by hemoglobin, including all structural
For each of the following reactions at equilibrium indicate if the equilibrium mixture contains mostly products mostly reactants or both products and reactants: a)2H2O(g) 2H2(g)+O2(g) Kc=4x10^-48. b)N2(g)+3H2(g) 2NH3(g) Kc=0.30. c)2SO2(g)+O2(g) 2S..
200 million over a five year period. how many dollars is that paid per second?
The masses of the unknown and the solvent (water) were determinded, and the unknown completely dissolved in the water. Just before the jacketed test tube containing the unknown solution was placed in the ice-salt water bath
What complementary functional group would need to be present in the neuraminidase active site for (a) hydrogen bonding and (b) ionic interactions to oseltamivir to be observed?
Consider the reaction: Cu^2+(aq) + 4NH3 (aq) -> Cu(NH3)4^2+(aq) Kf=2.1 x 10^13 If Ksp for Cu(OH)2 is 2.2 x 10^-20, what is the value of the equilibrium constant, K, for the reaction below? Cu(NH3)4^2+(aq) + 2OH -> Cu(OH)2(s) + 4NH3(aq)
if you doubled the volume of solution and kept the quanties of the reactants the same what would happen to the reaction
What would happen if you increase the pH of this acidic solution by addition of a strong base such as KOH? b.) Write the balanced equation for the reaction (a.) and identify both the stronger acid and base and the weaker acid and base.
