A voltaic cell is an electrochemical cell that uses a chemical reaction to produce electrical energy. 1  The anode is an electrode where oxidation occurs. 2  The cathode is an electrode where reduction occurs.  A salt bridge is a chamber of electrolytes necessary to complete the circuit in a voltaic cell.
KEY ENERGY PROCESSES IN CELLS. Most of what a cell does involves endergonic reactions, requiring constant energy input; these reactions are coupled to just a few exergonic reactions which supply that energy. The key fuel source in cell reactions is Adenosine Triphosphate, or ATP.ost of what a cell does involves endergonic reactions, requiring constant energy input; these reactions are coupled to just a few exergonic reactions which supply that energy.
