Re: [DIYbio] Re: Thermogenesis via leaky mito membranes, is the proton channel getting hot or does the proton react?

A bit of duckduckgo-ing yields:
https://en.wikipedia.org/wiki/Thermogenin
https://en.wikipedia.org/wiki/Uncoupling_protein

..but also corrects my supposition that this is behind normal
thermogenesis in mammals. There is in fact no mention of how heat is
generated in the Liver, whether by this or some other means. According
to the articles on non-shivering thermogenesis, it's used by infants
and hibernating mammals; this suggests something else is afoot in
normal thermogenesis for adult actives.

And yea, the decouplers seem to just allow protons to move through
without involvement of electron transport chains, so it's not free
electrons, just the dumping of potential energy from the proton
gradient. How this yields heat in "common sense" terms is probably hard
to explain, I don't understand it myself; as you say, it's all down to
an increase in entropy. :)
