Abstract

Cell metabolism requires transmembrane proton and electrochemical gradients to synthesize adenosine 5′-triphosphate (ATP), translocate ions, proteins and metabolites and regulate other vital activities.

Keywords:

  • adenosine-5′-triphosphate;
  • chemiosmosis;
  • photophosphorylation;
  • oxidative phosphorylation;
  • proton electrochemical potential gradient
