Cyclic electron transfer in plant leaf.
The turnover of linear and cyclic electron flows has been determined in fragments of dark-adapted spinach leaf by measuring the kinetics of fluorescence yield and of the transmembrane electrical potential changes under saturating illumination. When Photosystem (PS) II is inhibited, a cyclic electron flow around PSI operates transiently at a rate close to the maximum turnover of photosynthesis. ...

متن کاملRespiratory electron transfer pathways in plant mitochondria
The respiratory electron transport chain (ETC) couples electron transfer from organic substrates onto molecular oxygen with proton translocation across the inner mitochondrial membrane. The resulting proton gradient is used by the ATP synthase complex for ATP formation. In plants, the ETC is especially intricate. Besides the "classical" oxidoreductase complexes (complex I-IV) and the mobile ele...
متن کاملPlant Mitochondrial Electron Transfer and Molecular Biology.
Aerobic respiration, a process performed by all plants, involves the controlled oxidation of metabolites containing reduced carbon to produce carbon dioxide and water as the final products (Taiz and Zeiger, 1991). Severa1 types of reduced carbon compounds, including fatty acids, organic acids, and amino acids, can serve as the primary reducing substrates for plant respiration. However, the most...
متن کاملElectron Transfer in Dye-Sensitized Nanocrystalline TiO2 Solar Cell
The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...
