Example sentences for: redox
How can you use “redox” in a sentence? Here are some example sentences to help you improve your vocabulary:
Recent ideas on the origin of life suggest that early cellular structures were abiotic iron-sulfur formations at submarine hydrothermal vents in the Hadean ocean, in which basic biochemical and metabolic processes could have developed before the formation of cell membranes [ 39 40 ] . As well as iron and sulfur, hydrothermal areas are often are often characterized by high levels of arsenic [ 41 ] and may even contain arsenic redox active microbial communities [ 42 ] . Given the integral role of phosphate in early (and current) cellular metabolism [ 39 ] , an ability to reduce the levels of arsenate (a phosphate analog) might have been an essential biochemical process.
Despite the suggestion of HGT and duplication events, the arsC phylogeny suggests that arsenate reductase is an evolutionarily old enzyme, a hypothesis that was recently suggested for arsenite oxidase [ 38 ] . This is the first phylogenetic analysis of an arsenic redox active gene to include all three domains and the Archaea and Bacteria were clearly separated, with S. cerevisiae subsequently branching from Archaea.
Since DCIP and XTT have different redox potentials, and XTT in our work appears to generally be more easily reduced by soil microbial communities, this shows a need to use more than one respiratory dye in this type of experiment.
Biochemical studies have pointed out that the PRC-barrel of the purple bacterial PRC-H lies on the cytosolic face of the reaction center and directly affects the redox processes during the photosynthetic reaction [ 16, 28].
Since living entities require a continual source of usable energy, we should be able to detect a chemical signature of life in the form of mixtures of redox molecules such as porphyrins, quinones, and flavins that transport electrons along redox gradients between electron donors and acceptors [ 13 ] . We examined methods to extract and detect the components of electron transport chains that might be used to indicate the presence of life on site in extraterrestrial locations.
