The organic platform provides a venue for the cells to perform their various and often unique functions. Cells of this sort and, cells of that sort, divide the tasks necessary to maintain our existence. Each cell in our body needs energy and heat in order to carryout their designed directions from this stuff called the genetic code. Would you believe that it is the "cosmic thread" [electron] that provides this energy, passing itself along a series of steps to produce the energy necessary to maintain each cell.
"High energy bonds" they are called. Giving themselves up to generate this energy, they pass to "a lower energy bond" which is then in need of oxygen. The "lower energy bond" takes new electrons from the oxygen, producing another "high energy bond". On and on it goes producing a continual source of energy for the cell. It takes a whole host of nutrients to fuel these cells, but hey, an apple a day keeps the doctor away they say.
For those interested, this is known as "Stoichiometric Control". The "high energy bonds" are housed in what is called "Adenosine triphosphate" = ATP. The lower energy bonds are housed in what is called "Adenosine diphosphate" = ADP. ATP to ADP and back again...a thread that binds.
