In bacterial cells, the electron transport system is located in the. A. cell membrane. B. mitochondria. C. chloroplasts. D. ribosomes.E. cytoplasm.n bacterial cells, the electron transport system is located in the. A. cell membrane. B. mitochondria. C. chloroplasts. D. ribosomes.
An electron transport chain(ETC) couples a chemical reaction between an electron donor (such as NADH) and an electron acceptor (such as O2) to the transfer of H+ ions across a â¦ membrane, through a set of mediating biochemical reactions.ncorrect: Some bacteria do not have an electron transport chain and just glycolysis. If they do have an electron transport chain, then it would take place in the mitochondria.
