how do eubacteria synthesize ATP?

[rakuenso]

If i recall correctly, eubacteria such as e coli lack energy powerhouses such as the mitochondria and choroplast. So does anyone know a link that provides extensive detail as to how they synthesize ATP from molecules such as glucose?

Perhaps they use their outer membrane to set up a proton gradient which drives ATP synthetase, like mitochodria, Im not sure, just speculating/educated guess.

Hi rakuenso,

sorcerer is right, bacteria (prokaryotes) lack the mitochindria organelles which normally drive the ATP synthesis in our cells. But the alternative way to synthisizing ATP is setting up a proton gradient over the inner membrane (between the periplasmatic space and the cytosolic space) which "spins" the ATP-synthase making the ATP.

 

(I don't have a link, i can refer to the book The CELL by Alberts et al.)
