Evolution under the sun: optimizing light harvesting in photosynthesis.
The emergence and evolution of life on our planet was possible because the sun provides energy to our biosphere. Indeed, all life forms need energy for existence and proliferation in space and time. Light-energy conversion takes place in photosynthetic organisms that evolve in various environments featuring an impressive range of light intensities that span several orders of magnitude. This pro...
متن کاملDynamics of light harvesting in photosynthesis.
We review recent theoretical and experimental advances in the elucidation of the dynamics of light harvesting in photosynthesis, focusing on recent theoretical developments in structure-based modeling of electronic excitations in photosynthetic complexes and critically examining theoretical models for excitation energy transfer. We then briefly describe two-dimensional electronic spectroscopy a...
متن کاملOptimization and evolution of light harvesting in photosynthesis: the role of antenna chlorophyll conserved between photosystem II and photosystem I.
The efficiency of oxygenic photosynthesis depends on the presence of core antenna chlorophyll closely associated with the photochemical reaction centers of both photosystem II (PSII) and photosystem I (PSI). Although the number and overall arrangement of these chlorophylls in PSII and PSI differ, structural comparison reveals a cluster of 26 conserved chlorophylls in nearly identical positions ...

عصر روشنگری زمان شکل گیری ایده های مدرن تربیتی- آموزشی بود اما تاکید بیش از اندازه ی دوشاخه مهم فلسفی زمان یعنی عقل گرایی و حس گرایی بر دقت و وضوح، انسان عصر روشنگری را نسبت به دیگر تواناییهایش نابینا کرده و موجب به وجود آمدن افرادی تک بعدی شد که افتخارعقلانیتشان، تاکید شان بر تجربه فردی، به مبارزه طلبیدن منطق نیاکانشان وافسون زدایی شان از دنیا وتمام آنچه با حواس پنجگانه قابل درک نبوده و یا در ...
Cyanobacterial photosynthesis in the oceans: the origins and significance of divergent light-harvesting strategies.
Prochlorococcus and Synechococcus are abundant unicellular cyanobacteria and major participants in global carbon cycles. Although they are closely related and often coexist in the same ocean habitat, they possess very different photosynthetic light-harvesting antennas. Whereas Synechococcus and the majority of cyanobacteria use phycobilisomes, Prochlorococcus has evolved to use a chlorophyll a(...
