question about aerobic bacteria

sorry if this is a really basic question but please bear with me
i'm a bit weak in bio because my major has nothing to do with bio

question:

if a bacteria is aerobic obligate, and bacteria don't have membrane bound organelles(ie mitochondria), how does it use the 02?

it doesn't do the kreb cycle so it doesn't need O2 does it?

i guess it does glycolysis and uses the NADH from glycolysis to make ATP at the electron transport chain? is the ETC at the plasma membrane of the bacteria?


which also leads me to ask, how does anaerobic bacteria create ATP?
not sure about this either

i suck at bio 😳

please help

thank you!!

Bacteria and other prokaryotes do not have a membrane-bound nucleus or other organelles. It uses O2 in its electron transport system which is different from the cytochrome system present in eukaryotes. Glycolysis and the electron transport system create ATP.

i think it also occurs across the cell membrane

prokaryotic bacteria use their cell membrane as opposed to mitochondria to make use of O2!
