You guys have made reference several times to the cellular energy system, the need to find a place to put the extra electrons, etc. Do you have a good reference to a writeup about this, for those of us whose last biology class was a very long time ago? It’s clear that this is a really important thing to understand.
Is the effect of silver nanoparticles related to this? What determines which metals will be antimicrobial (copper, silver) and which won’t be (iron)?
This is a good site for brushing up on electron transport:
http://www.elmhurst.edu/~chm/vchembook/596electransport.html. Also,
the Wikipedia entry on this topic is very well done:
http://en.wikipedia.org/wiki/Electron_transport_chain. As for your
other questions, I’ll read them on an upcoming episode to get the
others’ opinions.
I suppose it depends on how you look at it. There’s usually another way. http://www.christianlouboutinssite.com
If this Desulfouibrio bacteria is a contributor to autism how can this be killed off and with what specifi antibiotican fo what period of time, would you also suggest molybdnum supplmentation?
