Primary Electron Transfer in Photosynthetic Reaction Centers

enhancement of the T-d8 concentration relative to EtOH (bulk solution has a value of =0.25) followed by a near-linear decrease after the break. Returning to the Fickian solution and using the slower turn on of the surface concentration could represent the EtOH diffusion into the polystyrene. Figure 9 with a = 1 would be indicative if an induction period was included. That the EtOH is constraine...

Electron transfer in the photosynthetic reaction center.

Photosynthesis occurs via electron transfer between pigment molecules or prosthetic groups embedded in a thylakoid membrane protein complex. These pigments form the “conductive pathway” for electron flow and the surrounding protein serves as a“shaping insulator”. Electron transfer through the protein proceeds via quantum tunneling into succesively lower potential wells represented by the pigmen...

The Gas Phase Oxidation of Acetaldehyde Reaction Mechanism and Kinetics

The mechanism of the low temperature oxidation of gaseous acetaldehyde was investigated in the temperature range of 1 50-400?°C. The minor, intermediate and major products were identified and measured quantitatively by sampling directly into the ionization chamber of an MS10-C2 mass spectrometer from the reactor. The formation of H2O, CO, CO2, HCOOH, H2, HCHO, CH3COOH and CH3OH as the major pro...

Proton and electron transfer in bacterial reaction centers.

The bacterial reaction center couples light-induced electron transfer to proton pumping across the membrane by reactions of a quinone molecule Q(B) that binds two electrons and two protons at the active site. This article reviews recent experimental work on the mechanism of the proton-coupled electron transfer and the pathways for proton transfer to the Q(B) site. The mechanism of the first ele...
