Transport bicycles

open access: yesProceedings of the National Academy of Sciences, 1997
Uphill transport of one substrate (the driven substrate) can be coupled to the dissipation of an electrochemical potential gradient of another substrate (the driving substrate), to an exergonic chemical reaction, or to a photoreaction. In all cases, the driven substrate is taken up from a low concentration (or relatively low electrochemical potential ...
