How do cells put electrons to rest? Using a minimal pathway to get rid of excess metabolic electrons, diverse environmentally important microbes overcome large spatial, kinetic, and thermodynamic barriers in order to survive in extreme anoxic conditions.
I understood some of those words.
In reality the issue is a cultural contrast of androgynous terms with respect to the juxtaposition of the quantum casuistic orientation. Perhaps exogenous parameters should be considered with respect to Socratic philosophy, at least with respect to the genesis of this question from a position of initiation of ancient thought.
I do not want to finish my contribution to your interesting intervention without recommending the book: “The sidereal feeling of past constellations”, there it goes into depth about the quantum philosophy applied to the singularity of a cold beer, perhaps it will be of interest to you…
Joke apart, here a simplificate explnation:
Scientists discovered how bacteria are able to quickly transfer electrons outside of their cells over long distances. Certain bacteria have tiny conductive wires on their surface called nanowires that allow them to get rid of electrons produced during respiration. This process of getting rid of electrons to external materials is called extracellular electron transfer (EET). It was unclear how the electrons travel so fast from inside the cell onto the surface nanowires through the crowded space inside the bacteria. The new research shows that special proteins called cytochromes in the bacterial periplasm directly inject electrons into the nanowires.
Five different cytochromes named PpcA, PpcB, PpcC, PpcD and PpcE were found to be able to transfer electrons to the nanowires made of a protein called OmcS. PpcC transferred electrons most efficiently even though it was the least abundant. The cytochromes bind transiently to OmcS using complementary positive and negative charges on their surfaces. This allows the heme groups where the electrons are carried to come into close contact. The researchers also accurately measured the potential energy level of the OmcS nanowires to be -130 mV, which makes electron transfer thermodynamically favorable from the higher potential cytochromes. This direct injection pathway into OmcS nanowires seems to be common in many bacteria that use EET to thrive in diverse environments.
Overall, by identifying how electrons can rapidly move from inside cells onto conductive nanowires on the surface using Ppc cytochromes, the research provides key insights into how some bacteria can proliferate quickly in extreme environments. Understanding EET pathways could also help design better microbial communities for applications like bioremediation, bioenergy and bioelectronics.
