Flash Polarographic Detection of Superoxide Production as a Means of Monitoring Electron Flow between Photosystems I and Ii
نویسنده
چکیده
In isolated chloroplasts exogenous low potential electron acceptors, such as methyl viologen (MV), have been used to study the chloroplast electron transport involving photosystem I. The reduction of acceptors and their consequent autoxidation [I] can most easily be followed polarographically by the uptake of 0:. The reactions which are believed to occur [2,3] when two electrons are transferred from water to MY are as follows:

Effects of short-time alkaline pretreatment on growth and photosynthesis efficiency of endemic cyanobacterium Fischerella sp. FS 18.
Alkaline pH is one of the most important problems of our aquatic habitat. We used Stigonematalean native cyanobacterium Fischerella sp. FS 18 as our model strain, andstudied it under different alkaline pHs (7, 9 and rarely 11) under two different – short and long- time treatments (24 and 96 hours after inoculation). Spectroscopic results showed that both alkalinity and time affected growth rate...

Filamentous Cyanobacteria. Hydrogen Peroxide, Photosystem II. Nitrogen Metabolism By means of mass spectrometric analysis we have been able to demonstrate H20 2-production and its decomposition by photosystem II in thylakoids of the filamentous cyanobacterium Oscil latoria chalybea. This H 2Ö 2-production and its quasi simultaneous decomposition by the S-state system can be readily demonstrate...
متن کاملA robust wavelet based profile monitoring and change point detection using S-estimator and clustering
Some quality characteristics are well defined when treated as response variables and are related to some independent variables. This relationship is called a profile. Parametric models, such as linear models, may be used to model profiles. However, in practical applications due to the complexity of many processes it is not usually possible to model a process using parametric models.In these cas...
متن کاملPlastocyanin as the possible site of photosynthetic electron transport inhibition by glutaraldehyde.
Treatment of spinach chloroplasts with glutaraldehyde causes an inhibition in the electron transport chain between the two photosystems. Measurements of O(2) flash yields, pH exchange, and fluorescence induction show that the O(2) evolving apparatus, photosystem II and its electron acceptor pool are not affected. The behavior of P700 indicates that its reduction but not its oxidation, is severe...
متن کاملPhotosystems I and II
Within the thylakoid membranes of the chloroplast, are two photosystems. Photosystem I optimally absorbs photons of a wavelength of 700 nm. Photosystem II optimally absorbs photons of a wavelength of 680 nm. The numbers indicate the order in which the photosystems were discovered, not the order of electron transfer. Under normal conditions electrons flow from PSII through cytochrome bf (a membr...
