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. The molecule is an amino acid linked to a ribose sugar, linked to a string of three phosphate groups (there are also ADP, Adenosine Diphosphate, and AMP, Adenosine Monophosphate).
From Wikipedia, the free encyclopedia. A microbial fuel cell (MFC) or biological fuel cell is a bio-electrochemical system that drives a current by using bacteria and mimicking bacterial interactions found in nature.MFCs can be grouped into two general categories, those that use a mediator and those that are mediator-less. microbial fuel cell is a device that converts chemical energy to electrical energy by the catalytic reaction of microorganisms. A typical microbial fuel cell consists of anode and cathode compartments separated by a cation (positively charged ion) specific membrane.
