Abstract Fermentation, photosynthesis and respiration are energy-conversion processes in which chemical energy or light-energy is sequentially transduced into redox energy, acid-base energy and, eventually, metaphosphate-orthophosphate energy. Fermentation is a prime energy-yielding anaerobic process, whereas photosynthesis and respiration are later-developed processes that involve, respectively, the light-driven oxidation of water to free oxygen by the oxidized primordial bioelements carbon… CONTINUE READING
