The potexvirus pepino mosaic virus (PepMV) is pandemic in tomato crops. Previously we modeled the structure of ...Reaction 7, however, is unlikely to take place due to its relatively high standard potential (1.36 V/SHE). The cathode reduction reactions mainly involve dissolved oxygen reduction reactions (ORR), and among them, the following is most probable in our case due to its small standard potential of 0.69 V/SHE: 36Sep 25, 2022 · „the higher the potential, the higher the dissolved oxygen in medium“. I think the wording is misleading, since high redox potential is a consequence of oxygen being present, not the other way around (as that would imply something like high redox potential attracting atmospheric oxygen into water). Aerobic organisms requiring high oxygen levels (high redox potential) possess low-affinity aerobic cytochrome oxidases (Cco, Cta, Qox, Cyo) 16.Oct 1, 2019 · A high redox potential of the cathode is desirable to catch the protons.
