Book Synopsis Non-Photochemical Quenching and Energy Dissipation in Plants, Algae and Cyanobacteria by : Barbara Demmig-Adams
Download or read book Non-Photochemical Quenching and Energy Dissipation in Plants, Algae and Cyanobacteria written by Barbara Demmig-Adams and published by Springer. This book was released on 2016-10-02 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harnessing the sun’s energy via photosynthesis is at the core of sustainable production of food, fuel, and materials by plants, algae, and cyanobacteria. Photosynthesis depends on photoprotection against intense sunlight, starting with the safe removal of excess excitation energy from the light-harvesting system, which can be quickly and non-destructively assessed via non-photochemical quenching of chlorophyll fluorescence (NPQ). By placing NPQ into the context of whole-organism function, this book aims to contribute towards identification of plant and algal lines with superior stress resistance and productivity. By addressing agreements and open questions concerning photoprotection’s molecular mechanisms, this book contributes towards development of artificial photosynthetic systems. A comprehensive picture –from single molecules to organisms in ecosystems, and from leading expert’s views to practical information for non-specialists on NPQ measurement and terminology – is presented.
Book Synopsis The Biophysics of Photosynthesis by : John Golbeck
Download or read book The Biophysics of Photosynthesis written by John Golbeck and published by Springer. This book was released on 2014-08-07 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume is intended as an introduction to the physical principles governing the main processes that occur in photosynthesis, with emphasis on the light reactions and electron transport chain. A unique feature of the photosynthetic apparatus is the fact that the molecular structures are known in detail for essentially all of its major components. The availability of this data has allowed their functions to be probed at a very fundamental level to discover the design principles that have guided evolution. Other volumes on photosynthesis have tended to focus on single components or on a specific set of biophysical techniques, and the authors’ goal is to provide new researchers with an introduction to the overall field of photosynthesis. The book is divided into sections, each dealing with one of the main physical processes in photosynthetic energy conversion. Each section has several chapters each describing the role that a basic physical property, such as charge or spin, plays in governing the process being discussed. The chapters proceed in an orderly fashion from a quantum mechanical description of early processes on an ultrafast timescale to a classical treatment of electron transfer and catalysis on a biochemical timescale culminating in evolutionary principles on a geological timescale.

Book Synopsis The Photosynthetic Membrane by : Alexander V. Ruban
Download or read book The Photosynthetic Membrane written by Alexander V. Ruban and published by John Wiley & Sons. This book was released on 2012-09-17 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proteins that gather light for plant photosynthesis are embedded within cell membranes in a site called the thylakoid membrane (or the "photosynthetic membrane"). These proteins form the light harvesting antenna that feeds with energy a number of vital photosynthetic processes such as water oxidation and oxygen evolution, the pumping of protons across the thylakoid membranes coupled with the electron transport chain of the photosystems and cytochrome b6f complex, and ATP synthesis by ATP synthase utilizing the generated proton gradient. The Photosynthetic Membrane: Molecular Mechanisms and Biophysics of Light Harvesting is an introduction to the fundamental design and function of the light harvesting photosynthetic membrane, one of the most common and most important structures of life. It describes the underlying structure of the membrane, the variety and roles of the membrane proteins, the atomic structures of light harvesting complexes and their macromolecular assemblies, the molecular mechanisms and dynamics of light harvesting and primary energy transformations, and the broad range of adaptations to different light environments. The book shows, using the example of the photosynthetic membrane, how complex biological structures utilize principles of chemistry and physics in order to carry out biological functions. The Photosynthetic Membrane: Molecular Mechanisms of Light Harvesting will appeal to a wide audience of undergraduate and postgraduate students as well as researchers working in the fields of biochemistry, molecular biology, biophysics, plant science and bioengineering.

Book Synopsis Multidimensional Ultrafast Spectroscopy of Photosynthetic Pigment-Protein Complexes by : Eleonora De Re
Download or read book Multidimensional Ultrafast Spectroscopy of Photosynthetic Pigment-Protein Complexes written by Eleonora De Re and published by . This book was released on 2014 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents the application of ultrafast spectroscopy to the investigation of pigment-protein complexes (PPCs) involved in energy transfer and energy dissipation in photosynthetic organisms. PPCs are the building blocks of all photosynthetic organisms, and within individual pigment-protein complexes, energy transfer dynamics occur over fast timescales and broad spectral regions. Chapter 1 gives an introduction to the capability of photosynthetic organisms to absorb light energy, funnel this energy to a location for charge separation, and perform charge separation with subsequent conversion into chemical energy. All of these functions need to be performed efficiently under different light conditions. This chapter also includes a discussion of the different light harvesting strategies that various photosynthetic organisms have evolved. Lastly, this chapter discusses the application of ultrafast spectroscopy as an excellent tool to study the dynamics of PPCs. The three experimental techniques used in this dissertation are introduced in this chapter. Chapters 2 and 3 present the application of two ultrafast spectroscopic techniques, two dimensional electronic spectroscopy and transient absorption spectroscopy, to the investigation of the structure-function relationship of photosynthetic pigment-protein complexes. Chapter 2 is an investigation of the photophysics of the two forms of the Orange Carotenoid Protein, involved in excess energy dissipation in cyanobacteria. Ultrafast spectroscopy allows us to understand how a conformational change that modifies pigment-protein interactions is able to generate a different biological function. Chapter 3 presents degenerate and non-degenerate two dimensional electronic spectroscopy experiments to investigate the energy transfer dynamics and couplings in the bacterial reaction center, which is the location of charge separation. Chapter 4 investigates a PPC involved in excess energy dissipation in green algae, LhcSR. Fluorescence lifetime spectroscopy is used to investigate the excited state properties of LhcSR, which plays a role as light harvester, pH sensor and quencher in algae. The results allow us to identify two conformations, a light harvesting one and a quenching one. Transient absorption spectroscopy is used to investigate the energy transfer pathways involved in quenching in the two different conformations. Finally, Chapter 5 presents conclusions and extensions to future work, in order to improve our understanding of the energy transfer dynamics in natural photosynthetic systems.
Book Synopsis Photosynthetic Excitons by : Herbert van Amerongen
Download or read book Photosynthetic Excitons written by Herbert van Amerongen and published by World Scientific. This book was released on 2000 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excitons are considered as the basic concept used by describing the spectral properties of photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light-harvesting antenna and reaction centers. Following the recently obtained structures of a variety of photosynthetic pigment-protein complexes from plants and bacteria our interest in understanding the relation between structure, function and spectroscopy has strongly increased. These data demonstrate a short interpigment distance (of the order of 1 nm or even smaller) and/or a highly symmetric (ring-like) arrangement of pigment molecules in peripheral light-harvesting complexes of photosynthetic bacteria. Books which were devoted to the exciton problem so far mainly considered the spectral properties of molecular crystals. However, the small size of these pigment aggregates in the pigment-protein complexes as well as the role of the protein, which is responsible for the structural arrangement of the complex, clearly will have a dramatic influence on the pigment spectra and exciton dynamics. All these aspects of the problem are considered in this book. Exciton theory is mainly considered for small molecular aggregates (dimers, ring-like structures etc.). Together with the theoretical description of the classical conceptual approach, which mainly deals with polarization properties of the absorption and fluorescence spectra, the nonlinear femtosecond spectroscopy which is widely used for investigations now is also discussed. A large part of the book demonstrates the excitonic effects in a multitude of photosynthetic pigment-protein complexes and how we can understand these properties on the basis of the exciton concept.
