Výzkum primárních procesů fotosyntézy probíhá na trojmezí tří velkých přírodních věd: fyziky, chemie a biologie. Předmětem tohoto článku je stručný přehled sledu elementráních chemických a fyzikálních pochodů od záchytu fotonu po syntézu adenosintrifosfátu (ATP) a úvod do kvantové teorie světlosběrných fotosyntetických antén., Research of primary processes of photosynthesis occurs at the boundary of three great natural sciences: physics, chemistry and biology. This article gives a brief overview of the elementary chemical and physical processes from the absorption of a photon to the synthesis of adenosintriphosphate molecules, and it introduces the reader to the theory of photosynthetic light-harvesting antennae., Tomáš Mančal., and Obsahuje bibliografii
Current scientific theories strive to find one theory, which would describe the origin of life on Earth, but so far none were successful. To succeed i this field, one has to broader their view and accompany the scientific question with philosophy and set firmly the framework of research and define its borders. In order to assess the philosophical part of the work, one needs not to resort to new ideas only, because men and women in the past have already expressed their thoughts. They are however nowadays remembered only in history of arts and philosophy. In our recent article published in Nature Astronomy, we presented a very complex model for the creation of methane and its reprocessing to more complex organic molecules including nucleic acid bases from simple gaseous precursors. The purpose of this work is to show the reoeating cycle of the creation of complex molecules from CO2 and their subsequent destruction back to their basic parent molecules in comparison with the idea of Hieronymus Bosch. and Svatopluk Civiš.
Zévy (Tridacnidae) jsou mezi mořskými mlži výjimečné velikostí i způsobem získávání potravy. V jejich plášti se vyskytují mikroskopické řasy zooxantely, které fotosyntézou produkují sacharidy, o něž se dělí s hostitelem. Za nápadné zbarvení pláště vděčí zévy zooxantelám a specializovaným buňkám iridocytům., Giant clams (Tridacnidae) are exceptional among sea clams for their size and the way they acquire food. On their shells microscopic zooxanthella algae occur, producing saccharides through photosynthesis, which they share with the host. The conspicuous coloring of the shells is due to the clams’ zooxanthellae and specialized iridocyte cells., and Nicole Černohorská.
