Maintenance of an optimal redox environment is critical for appropriate functioning of cellular processes and cell survival. Despite the importance of maintaining redox homeostasis, it is not clear how the optimal redox potential is sensed and set, and the processes that impact redox on a cellular/organellar level are poorly understood. The genetic bases of cellular redox homeostasis were inves...
Reduction-oxidation (redox) reactions are an essential part of cell metabolism and represent a major fraction of all catabolic and anabolic reactions. Their dominant characteristic is that they generate and consume compounds with in part highly negative redox potential. Redox reactions occur at many sites in the cell, e.g. in membranes such as thylakoids, plastid envelope, and plasma membrane a...
Introduction: oxygen supplementation and total parenteral solution (TPN) are two main clinical practices that sustain oxidative stress. Glutathione is a key molecule that detoxifies peroxides resulting in a more oxidized redox potential. We hypothesize that O2 supplementation and longer TPN duration are associated with both more oxidized redox potential and more severe bronchopulmonary dysplasi...
Recent experiments with bacteria have shown that light and oxygen can control gene expression through effects on oxidation-reduction potential. The term "redox sensor" is proposed as a general term for electron carriers that initiate control of gene expression upon oxidation or reduction. The term "redox response regulator" is proposed for DNA-binding proteins that modify gene expression as a r...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
