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. WebJan 30, 2024 · Exogenous carbon-mediated inactivation by aminoglycoside antibiotics is attributed to elevated NADH and proton motive force (PMF) generation and increased antibiotic uptake ( 10 – 13 ), which is supported by metabolic modulation, including promotion of the tricarboxylic acid (TCA) cycle ( 11, 12 ).
