      The temperature dependence of photoinduced electron transfer reactions of phthalalocyanine- and porphyrin-fullerene dyads, in which donor and acceptor moieties are covalently linked to each other, was studied. The dyads form an intramolecular exciplex as a transient state before the formation of the charge separation state. It was observed that the formation rates of the exciplex .   In cellular biology, the electron transport chain is one of the steps in your cell's processes that make energy from the foods you eat. It is the third step of aerobic cellular respiration. Cellular respiration is the term for how your body's cells make energy from food consumed.

Redox processes are at the heart of numerous functions in chemistry and biology, from long-range electron transfer in photosynthesis and respiration to catalysis in industrial and fuel cell research.

    Quantum biology is the study of applications of quantum mechanics and theoretical chemistry to biological objects and problems. Many biological processes involve the conversion of energy into forms that are usable for chemical transformations, and are quantum mechanical in nature. Such processes involve chemical reactions, light absorption, formation of excited electronic states, transfer of. The team will use this system to examine the challenges behind long-range electron transfer. “When a system contains thousands of loose parts, electron transfer is impacted by many factors,” says Jingcheng Huang, a postdoc in both the Kramer and Ducat labs. “The larger the system, the more unpredictable the electron transfer, compared to.

Electron Transfer in Chemistry and Biology provides a thorough and didactic approach to the theoretical basis of electron transfer phenomena.

Not only does it offer a full introduction to this area and a discussion of its historical development, it also gives detailed explanations of difficult issues, for example, long-range electron transfers.

The multi-heme c-type cytochrome OmcS, is one of the central components for extracellular electron transport in Geobacter sulfurreducens strain DL-1, but its role in other microbes, including other strains of G.

sulfurreducens is currently a matter of debate. Therefore, we investigated the function of OmcS in G. sulfurreducens strain KN, which is even more effective in extracellular.

In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is reduced to form water.

For example, a good deal of the energy we derive from. INTRODUCTION. Proton-coupled electron transfer is a fundamental mechanism in biology. Enzymes often rely on the coupling of electrons and protons to affect primary metabolic steps involving charge transport and catalysis ().Without the coupling of the proton and electron, many processes in biology would not be possible.

The quantum theory also predicts that electron transfer pathways could exhibit interference effects [22]. A detailed theoretical analysis of electron transfer through the azurin protein carried out by Regan and Onuchic suggested that quantum interferences between multiple distinct pathways play important roles in this protein [22,32, 33].

In the process, protons are pumped from the mitochondrial matrix to the intermembrane space, and oxygen is.

Inspatially separated redox reactions in the sulfidic and oxic zones of sediments were observed to be directly coupled to each other over centimeter distances in laboratory-incubated sediment, which was suggested to be accomplished via a direct electron transfer process rather than by the diffusion of molecules [17,18].This process is called electrogenic sulfide oxidation (e-SOx) and.

The data suggest that radical transport occurs via proton-coupled electron transfer (PCET) and that the protein structure has evolved to manage the proton and electron transfer co-ordinates in order to prevent 'off-pathway' reactivity and build-up of oxidised intermediates.Isotope Effects In Chemistry and Biology.

These phenomena imply that chirality and spin may play several important roles in biology, which have not been considered so far.
