Chemosynthesis

[PPonte]

First, sorry to put this topic in general discussion, but I haven’t found any proper category to place it.
I learnt chemosynthesis, but my text book and my teacher just give some ideas and not the full process. Some ideas are almost nothing to understand. For you to understand, I know that in chemosynthesis the energy to produce organic matter is obtained by oxidation of mineral substances. But for they being oxidated is necessary something to oxidate them, which substance does that? So, I ask you some links with detailed information about chemosynthesis for I hadn’t found anything interesting in google. Thank you very much!

A good start.

For more, try google.

I had already read that. Thank you very much, anyway. I just asked here because I cannot find anything interesting in google.

It is a complicated process. Read a microbiology book. they will offer a good start since chemosynthesis is carried out by bacteria.

hmm, oxygen?

Another link here:http://en.wikipedia.org/wiki/Chemoautotroph

You could probably find a great deal of info on http://www.scirus.com wher I found this for example. If you run another search with the author names you will probably find the number I and II of the serie.

what about if there are chemoautotrophs living without oxygen?
i actually have the same question.

Also, how do chemoautotrophs get energy from this oxidation and how do they use the energy? do they use the electron transport chain/oxidative phosphorylation the same way multicellular organisms do, or do they get their energy in a completely different way?
thanks! xx
