Question

Quizplus · Accepted Answer

The ETS (electron transport system) is embedded in the inner membrane of Gram-negative bacteria. This is because they have a double membrane structure, with the outer membrane being the first barrier to the external environment, and the inner membrane being the site of respiration and energy production. The ETS functions to transfer electrons and protons across the inner membrane, generating a proton gradient that drives ATP synthesis.
