In the cellular membrane.
Explanation:
In eukaryotes the electron transport chain (ETC) is situated in the mitochondiral membrane. Prokaryotes do not have organelles such as mitochondria, but they do have an ETC.
A membrane is required for the ETC to work, otherwise it would not be possible to build a gradient of hydrogen atoms. The only membrane in prokaryotes is the cellular membrane, that is where the ETC is located.
