The authors in the abstract given above describe the mechanism for the activation of metallothionein (MTF) that results in the detoxification of heavy metals. Use a diagram to illustrate and describe the cascade of events that occur as proposed by the authors. Use the pp2A pr110 complex in the discussion. Also make use of a pictures in diagram

Carbon monoxide and the cyanide ion are both toxic because they bind more strongly than Oxygen to the iron in hemoglobin (Hb) complex. Given the following equations: Hb + O2 HbO2 Keg = 2.0 x 1012 !3! Hb + CO ==== HBCO Kea = 1.0 x 1014 where ===m is the "double arrow" a) Write the balanced equation for the ligand exchange of Oz by CO. Calculate the equilibrium constant. b) Does the equilibrium favor reactants or products? Calculate the Standard Free Energy for the exchange.

Oxyhemoglobin, with an O2 bound to iron, is a low-spin Fe(II) complex; deoxyhemoglobin, without the O2 molecule, is a high-spin complex. A 15-minute exposure to air containing 400 ppm of CO causes about 10% of the hemoglobin in the blood to be converted into the carbon monoxide complex,called carboxyhemoglobin. What does this suggest about the relative equilibrium constants for binding of carbon monoxide and O2 to hemoglobin?

In general, would you expect EDTA4- to coordinate to transition metal ions more or less strongly than ethylenediamine does? Justify your answer with a reason other than the different charges on the two ligands.

Write all the isomers of [PtCl(CO)(PMe3)(C2H4)]+ and use the trans directing effect of ligands to suggest the reaction pathways to synthesize the above isomers from [PtCl4] 2-

Name the following coordination compounds using (a) stock system and (b) Ewing-Basset system. Use all small (lowercase) letters. Observe proper spacing, use of parenthesis and brackets, roman numerals for oxidation numbers, and normal numbers with + for positive charge and - for negative charge.

When Alfred Werner was developing the field of coordinationchemistry, it was argued by some that the opticalactivity he observed in the chiral complexes he hadprepared was due to the presence of carbon atoms in themolecule. To disprove this argument, Werner synthesizeda chiral complex of cobalt that had no carbon atoms in it,and he was able to resolve it into its enantiomers. Design acobalt(III) complex that would be chiral if it could be synthesizedand that contains no carbon atoms. (It may not bepossible to synthesize the complex you design, but we willnot worry about that for now.)

The IR spectrum of [Fe3(CO)12] has bands 2043, 2020, 1997 and 1840 cm-1. i) Explain the factors that influence the vibrational frequencies of coordinated carbonyl ligands. Include a diagram explaining the bonding model in a metal carbonyl complex. ii) Suggest a molecular structure for [Fe3(CO)12] and explain why it is consistent with the data above.
