The present paper represents a hypothetical structure, the structure for energy transformation (SET), which might be responsible for the proper energy transformation steps leading to the continuous production of H+ and ATP in living cells. We predict that the electron flow is realized through the electron flow device (EFD). We suppose that there are several versions of the SET. Two of them are described below [Structure of Aerobic Glycolysis (SET-AG) and Structure of Oxidative Phosphorylation (SET-OP). The hypothesis is based on the atom properties of the protonated adenine molecule and the docking computations of molecular mechanics involved, suggesting that two ascorbate molecules may occupy the empty NADPH pocket, preferably binding to the adenine binding site. We hypothesize that the adenine originates from uric acid (UA), resulting in an ATP-UA-ADP-ATP-UA cycle. It would also mean that UA is one of the oxygen sources in aerobic glycolysis. We also suppose that the EFD contains the well-known molecules of the Nicotinamide Adenine Dinucleotide (NAD) and Flavin Adenine Dinucleotide (FAD) supplemented with two additional UA-originated adenine molecules, two L-ascorbic acids, and two D-glucose molecules. Based on all this, we surmise that a tetra adenine octo phosphate ring (TAR) exists, in which the UA originated adenine molecules form a ring. The molecules are linked to each other through the N7-C2 and C8-N1 atoms of the adenine molecules by H2PO4e- molecules. The four N10 atoms of the adenine molecules bind one flavin, one nicotinamide, and two L-ascorbic acid molecules. Six D-glucose molecules complete one Unit of the structure. Both Fe-S and cytochrome clusters, as well as dehydrogenases, ensure the continuous operation of the Unit. The synchronized function of the three-stoke, three twin-cylinder engine results in continuous energy, ATP, and H+ production. Eukaryotic cells are equipped with the SET-AG and the SET-OP; thus, they can live in an anoxic and oxygenized environment. It is hoped that the SET concept developed here will help the better understanding the way of cancer treatment’s action regarding glucose deprivation or Vitamin C.
