bioelectricity

Bioelectricity deals with cell membrane transport processes that control the formation and dissipation of ion gradients. Ion gradients store energy in form of an electrochemical potential. This energy can be converted into other forms of energy. The electrochemical potential is available to organisms for biosynthesis (photosynthesis and respiration), transport of metabolites (absorption and secretion), mechanical work (bacterial flagella rotor, swimming, crawling), and signaling processes (action potentials). Action potentials are a form of information used by electrically excitable membranes to control the activity of cells (calcium signaling, muscle contractility) and to support or suppress communication between cells (release of chemical signaling molecules; hormones, neurotransmitters).
