The geothermal activity, liquid water, and redox reactions "give favorable conditions for life on Enceladus," says Parkinson.
In addition, redox reactions play a critical role in the regulation of energy metabolism.
More fundamental, however, is the problem that the speciation of arsenic change during transportation of samples to the laboratory and storage for analysis due to redox reactions and photochemical oxidation, so that the precise concentration of arsenic in the water itself is very difficult to ascertain.
The initial exposure to most toxic substances results in activation of cytochrome P450 (CYP) enzymes that attempt to produce water-soluble compounds capable of excretion by redox reactions (phase I metabolism).
That an RNA can assist in redox reactions might mean that before proteins evolved, primordial RNAs served as catalysts driving life-sustaining metabolic processes, the Mitsubishi Kasei scientist suggests.
For electron transfer reactions we have models for single electron transfers in well defined, relatively slow reaction, but we still have no explanation for the large number of very rapid multiple electron redox reactions.
Once inside mitochondria, an interaction with the electron transport chain reduces the copper from Cu(II) to Cu(I), resulting in a cascade of redox reactions, a rapid increase of oxidative stress, disruption of mitochondrial energy production, and the initiation of the mitochondrial apoptosis pathway.
Thus, they may act as catalysts for the redox reactions that produce reactive oxygen species (ROSs).

Neopterin and biopterin are by-products of the redox reactions involving tetrahydrobiopterin (BH4).
Since the report by Iyer and Szybalski (1964), the requirement for redox biotransformation of mitomycin C (MMC) has been well recognized in pharmacology, because MMC must be activated by a series of redox reactions leading to semiquinone derivatives coupled with ROS formation (Dusre et al.
