The synthesis of adenosine triphosphate (ATP), the universal biological energy currency, by oxidative phosphorylation and photophosphorylation catalyzed by the FOF1-ATP synthase is the fundamental means of cellular energy generation in animals, plants, and microorganisms. Since the ocean area and the amount of biomass is very large, the formation of ATP and its utilization by the myriad energy-consuming processes in the cell is the principal net chemical reaction taking place on the surface of the earth. This is indeed a most important reaction. How exactly does it occur? Since the development of the famous colorimetric assay for measurement of inorganic phosphate (Pi) in 1925, followed by the discovery of ATP in 1929, an enormous amount of research has been done to understand these intracellular energy-linked processes.

期刊介绍:
BioSystems encourages experimental, computational, and theoretical articles that link biology, evolutionary thinking, and the information processing sciences. The link areas form a circle that encompasses the fundamental nature of biological information processing, computational modeling of complex biological systems, evolutionary models of computation, the application of biological principles to the design of novel computing systems, and the use of biomolecular materials to synthesize artificial systems that capture essential principles of natural biological information processing.
