Where space, weight, and power limitations are of major importance, photosynthesis is an inefficient process for providing the energy for the production of food and oxygen. The assimilation of carbon dioxide into food materials by green plants requires two important factors commonly provided by the photosynthetic process, adenosine triphosphate ATP and reduced triphosphopyridine nucleotide TPNH. We have demonstrated that oxygen as well as enzymatically active TPNH can be generated by an electrochemical system which employs the mediating agents methyl viologen and ferredoxin-TPN-reductase. This system has been shown to stimulate TPNH-dependent fixation of carbon dioxide. It is recommended that further study be performed to allow greater understanding and definition of the system and its components, and to explore the possibility of producing ATP within the electrochemical cell.
