WebApr 1, 2024 · Bacteria also utilize their membrane potential as a means of signaling and processing information. By depolarizing the membrane potential, bacteria can enter a 'persister' state wherein they are more resistant to antibiotics. Homeostasis of pH is controlled by proton pumps, which maintain a PMF, and is thus dependent on the … WebDec 24, 2024 · This is used by fermenting bacteria, which lack an electron transport chain, and which hydrolyze ATP to make a proton gradient. Bacteria use these gradients for flagella and for the transportation of nutrients into the cell. In respiring bacteria under physiological conditions, ATP synthase, in general, runs in the opposite direction.
