In order to better understand the mechanisms of multiple-electron transfer reactions leading to high capacity in Fe3O4, a comprehensive investigation on local ionic transport and ordering is made by probing site occupancies of anions (O2) and cations (Li+, Fe3+/Fe2+) using multiple ...
Which type of membrane transport process uses ATP as a source of energy? What is ATP and how is it related to providing us with energy? What metabolic pathway begins the catabolism of glucose? What is the final electron acceptor in cellular respiration? How many ATP molecules are...
The peaks in the IC curves represent phase transitions during electrochemical reactions, which related to the plateaus in voltage profiles and valleys in DV curves, respectively. The peaks represent the battery capacity increase in certain voltage intervals. Compared with DV curves, IC curves present ...
How does the electron transport chain reform NAD and FAD from NADH and FADH2? Summarize the energy transfer that occurs in the light reactions. What drives the transport of electrons from NADH or FADH_2 to the final electron acceptor during respiration? Explain what would happen if durin...
During chemiosmosis,the free energy from the series of reactions that make up the electron transport chain is used to pump hydrogen ions across the membrane, establishing an electrochemical gradient. ... The production of ATP using the process of chemiosmosis in mitochondria is called oxidative phosp...
in an earlier study we proposed that the slow electrogenic reaction is due to two sequential reactions - (1) electron transfer from the b -cytochrome located near the inner surface of the thylakoid membrane to the b -cytochrome located near the outer surface, and (2) oxidation of the b -...
Tyrosyl radicals play essential roles in biological proton-coupled electron transfer (PCET) reactions. Ribonucleotide reductase (RNR) catalyzes the reduction of ribonucleotides and is vital in DNA replication in all subunits. In class la... Adam R. Offenbacher,Lori A. Burns,C. David Sherrill,....
A three-dimensional, reactive numerical flow model is developed that couples chemical reactions with density-dependent mass transport and fluid flow. The m... V Freedman,M Ibaraki - Wiley, 被引量: 50发表: 2002年 Particle-in-cell simulations of an alpha channeling scenario: electron current drive...
Proton release is discussed in terms of three main sources, namely the chemical production upon electron abstraction from water, protolytic reactions of Mn-ligands (e.g. oxo-bridges), and electrostatic response of neighboring amino acids. The extent of proton release differs between the four ...
much of oxygen's chemistry is driven by electron spin. the spin of oxygen had been considered. however, when spin is turned on, the required computation time will triple, even when using only the original cell. considering the computational cost, preliminary calculations were conducted on the pr...
