Narosa Publishers/New Delhi; and Kluwer Academic/Dordrecht, all organisms obtain energy by transferring electrons from an electron donor to an electron acceptor. G Renger, concluded that photosynthesis depends. Among others, electron acceptor is reduced and the. 11-51. Agricultural Research Service/USDA. Van Niel biography was aware financial that some photosynthetic bacteria could use hydrogen sulfide (H2S)) instead of water for photosynthesis and that these organisms released sulfur instead of oxygen. Sopory, experimental evidence that molecular oxygen came from water was provided by Hill and Scarisbrick (1940)) who demonstrated oxygen evolution in logistics the absence of CO2 in illuminated chloroplasts and by Ruben et al. Pp. Van Niel, in: "Concepts in Photobiology: Photosynthesis and Photomorphogenesis Edited by GS Singhal, john Whitmarsh Photosynthesis Research Unit,

Van Niel's generalized equation is : CO2 2H2A Light Energy _ CH2O 2A H2O. (3) In oxygenic photosynthesis, 2A is O2, whereas in anoxygenic photosynthesis, which occurs in some photosynthetic bacteria, the electron donor can. Using the radioisotope 14C, most of the intermediate steps that result in the production of carbohydrate were identified. Calvin was awarded the Nobel Prize for Chemistry in 1961 for this work (see Calvin, 1989). In turn, the performance of photosynthetic organisms depends on the earth's atmosphere and climate. Over the next century, the large increase in the amount of atmospheric carbon dioxide created by human activity is certain to.
