Biological electron-transfer reactions.
A wide range of biological processes makes extensive use of electron-transfer reactions. Rigorous characterization of a biological electron-transfer reaction requires a combination of kinetic, thermodynamic, structural and theoretical methods. The rate of electron transfer from an electron donor to an electron acceptor through a protein is dependent on the difference in reduction potential of t...
متن کاملLight Induced Electron Transfer Reactions of Metal Complexes
Properties of the excited states of tris(2,2'—bipyridine) and tris(l,lO—phenanthroline) complexes of chromium(III), iron(II), ruthenium(II), osmium(II), rhodium(III), and iridium(III) are described. The electron transfer reactions of the ground and excited states are discussed and interpreted in terms of the driving force for the reaction and the distortions of the excited states relative to th...
متن کاملExchange Reactions and Electron Transfer Reactions including Isotopic Exchange Theory of Oxidation-reduction Reactions Involving Electron Transfer
The mechanism for electron transfer is discussed in terms of an atomic motion on a potential-energy surface in many-dimensional atomic configuration space. In the absencc of electronic coupling between the reactants, a surface for the reactants intersects one for the products. Electronic coupling causes the usual removal of this degcncracy and permits the products to be formed adiabatically or ...
متن کاملThe interaction of energy and electron transfer reactions in mitochondria. IV. The pathway of electron transfer.
Two types of reaction have been described in which a reversal of electron transfer may occur: (a) energy-linked reduction of pyridine nucleotide in the presence of a flavin-linked substrate (I) and (b) energy-linked oxidation of cytochrome and reduction of pyridine nucleotide (2). In the latter, the presence of both oxidized and reduced forms of the respiratory carriers suggests that the system...
متن کاملKinetics of proton-coupled electron-transfer reactions
The kinetics of proton-coupled electron-transfer (pcet) reactions are reported for Mn4O4(O2PPh2)6, 1, and [Mn4O4(O2PPh2)6] , 1 , with phenothiazine (pzH). Both pcet reactions form 1H, by H transfer to 1 and by hydride transfer to 1 . Surprisingly, the rate constants differ by only 25% despite large differences in the formal charges and driving force. The driving force is proportional to the dif...
