Available in PDF, EPUB and Kindle. Book excerpt: According to its definition, synergetics is concerned with the cooperation of indi vidual parts of a system that produces macroscopic temporal, spatial or functional structures. A good deal of the volumes published within this series dealt with the formation of truly macroscopic structures which we can s. ee with our eyes. A common scheme could be developed to understand the formation of many patterns through self-organization. In particular, we have to use concepts which go beyond conventio nal thermodynamics. New ideas became crucial. We have to study kinetic processes, and often few highly excited degrees of freedom play the decisive role in the evo lution of structures. Over the past years it has turned out that quite similar lines of approach apply to a world which at first sight would be classified as "microsco pic". That world consists of processes in which biomolecules are involved. An impor tant example for the problems occurring there is provided by Manfred Eigen's theory of evolution of life at the molecular level (cf. his contribution to Volume 17 of this series). Another important example has been provided by Blumenfeld's book on problems of biological physics (Vol. 7 of this series). There it was proposed to treat biological molecules as machines which, in a certain sense, work through "macros copic" degrees of freedom.
Download or read book The Evolution of the Bioenergetic Processes written by E. Broda and published by Elsevier. This book was released on 2014-05-18 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Evolution of the Bioenergetic Processes deals with the evolution of the bioenergetic processes, from fermentation to photosynthesis and respiration, and their interrelationships in prokaryotes and eukaryotes. Topics covered range from the origin of life to the evolution of eobionts, organisms, and energy-rich compounds. Fermentation, photoorganotrophy, and photosynthesis in bacteria and plants are also discussed. Comprised of 25 chapters, this book begins with an overview of energy and entropy in the biosphere, followed by a detailed treatment of the evolution of bioenergetics based on the pattern of the bioenergetic processes in extant organisms. The reader is then introduced to the events involved in the origin of life; the evolution of eobionts and organisms; and the origin of energy-rich compounds, particularly nucleotides of the adenylic acid system. Subsequent chapters focus on fermentation and photosynthesis; assimilation of carbon dioxide; photoorganotrophy, chemolithotrophy, and photolithotrophy; and aerobic and anaerobic respiration of prokaryotes. The book also considers the energy supply of protozoa and fungi before concluding with an analysis of the history of atmospheric oxygen. This monograph will be of interest to evolutionary biologists.
Download or read book Principles of Bioenergetics written by Vladimir P. Skulachev and published by Springer Science & Business Media. This book was released on 2012-12-15 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.
Download or read book Foundations of Bioenergetics written by Harold Morowitz and published by Elsevier. This book was released on 2012-12-02 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Bioenergetics provides an introduction to the physical foundations of bioenergetics and the methods of applying these constructs to biological problems. It combines parts of thermal physics, biochemistry, ecology, and cellular and organismic biology into a single coherent work. Much of the material in this volume comes from ""Entropy for Biologists,"" an introductory thermodynamics book aimed particularly at life scientists. Some of the topics originally appeared in the monograph ""Energy Flow in Biology."" The current volume expands on that material with respect to biological applications and attempts to bridge the gap between physics and biology. The book explains basic concepts such as energy, temperature, the second law of thermodynamics, entropy, information theory, and statistical mechanics. It discusses the relations between thermodynamics and statistical mechanics, free-energy functions, radiant energy, the free energy of cells and tissue, chemical kinetics, and cyclic flows. It examines the relationships between energy flows and biological processes; applications of the concepts of Gibbs free energy, chemical potential, and activity; and measurements of temperature, energy, and thermochemical quantities. The book also includes chapters that deal with irreversible dynamics, irreversible theory, and osmotic flow.

Download or read book Bioenergetics written by Davor Juretic and published by CRC Press. This book was released on 2021-12-23 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics deals with the very first energy transformation steps performed by living cells. Increased dissipation is the primary effect of processing external energy packages. Enzyme-supported charge separation is the minor but essential outcome for maintaining life. This book explores the usefulness of dissecting the entropy production of enzymes involved in cellular defenses, fermentation, respiration, and photosynthesis, assuming that tightly regulated dissipation is the hallmark of life. Researchers, educators, and students of life sciences can find in this text many examples of how we can use the interdisciplinary approach to study cells' virtuoso ability to connect the microscopic to the macroscopic world. Each chapter is a self-contained unit with a glossary and selected references for further reading.
Download or read book Bioenergetics written by Peter Gräber and published by Birkhäuser. This book was released on 2012-12-06 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics, the topic of volume 5 of this Series, is concerned with the energetics, the kinetics, and the mechanisms of energy conversion in biological systems. This phenomenon can be investigated on diffe rent levels of complexity. On a global level the role of biological pro cesses for the steady state of our enviroment is considered. At the physiological level, the relation between energy input and the physiolo gical state of an organism is of interest, while at the cellular level the biochemical pathways for degradation and synthesis of all relevant substrates is investigated. At present the majority of bioenergetic stu dies pertain to the molecular level. The processes in a cell are cataly zed by a large number of proteins called enzymes. The enzymes in volved in energy transduction can be considered as molecular ma chines which transform energy from one form into another, or transfer energy from one process to another. Living systems operate far from equilibrium and are open in the ther modynamic sense, i. e. they exchange energy and matter with the sur roundings. Chapter 1 presents the principles of non equilibrium thermo dynamics applied to biological systems. About 0. 05% of the energy from the sunlight which reaches the surface of the earth is used by plants and algae as well as some bacteria to synthesize organic com pounds, and thus supplies all organisms with the energy necessary for life.

This book was released on 2007-10-31 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics is a term used to describe the events of primary energy transduction in biology. The field has seen tremendous advances in recent years thanks to developments in the biophysical and computational techniques used to solve the three-dimensional structures of the membrane-bound proteins, which often act as catalysts in these reactions. This has enabled researchers to bring, otherwise static, structures to life and decipher the dynamic function of these intriguing systems. Biophysical and Structural Aspects of Bioenergetics brings together contributions from internationally respected experts, all of whom helped shape and develop the field of bioenergetics. It provides a representative snapshot of the very latest key developments in this multidisciplinary subject, with an emphasis on molecular structure, and how this changes during the bioenergetic function. Offering a comprehensive overview of the current state of the art, and complete with extensive citations in each chapter, this book is the ideal reference for both biochemists and biophysicists studying this fascinating topic.

Available in PDF, EPUB and Kindle. Book excerpt: This book is aimed at a large audience: from students, who have a high school background in physics, mathematics, chemistry, and biology, to scien tists working in the fields of biophysics and biochemistry. The main aim of this book is to attempt to describe, in terms of physical chemistry and chemi cal physics, the peculiar features of "machines" having molecular dimen sions which play a crucial role in the most important biological processes, viz., energy transduction and enzyme catalysis. One of the purposes of this book is to analyze the physical background of the high efficiency of molecu lar machines functioning in the living cell. This book begins with a brief review of the subject (Chapter 1). Macro molecular energy-transducing complexes operate with thermal, chemical, and mechanical energy, therefore the appropriate framework to discuss the functioning of biopolymers comes from thermodynamics and chemical kinet ics. That is why we start our analysis with a consideration of the conventional approaches of thermodynamics and classical chemical kinetics, and their application to the description of bioenergetic processes (Chapter 2). Critical analysis of these approaches has led us to the conclusion that the conven tional approaches of physical chemistry to the description of the functioning of individual macromolecular devices, in many cases, appear to be incom plete. This prompted us to consider the general principles ofliving machinery from another point of view."
Download or read book The Biopsychosocial Model of Health and Disease written by Derek Bolton and published by Springer. This book was released on 2019-03-28 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is a systematic update of the philosophical and scientific foundations of the biopsychosocial model of health, disease and healthcare. First proposed by George Engel 40 years ago, the Biopsychosocial Model is much cited in healthcare settings worldwide, but has been increasingly criticised for being vague, lacking in content, and in need of reworking in the light of recent developments. The book confronts the rapid changes to psychological science, neuroscience, healthcare, and philosophy that have occurred since the model was first proposed and addresses key issues such as the model’s scientific basis, clinical utility, and philosophical coherence. The authors conceptualise biology and the psychosocial as in the same ontological space, interlinked by systems of communication-based regulatory control which constitute a new kind of causation. These are distinguished from physical and chemical laws, most clearly because they can break down, thus providing the basis for difference between health and disease. This work offers an urgent update to the model’s scientific and philosophical foundations, providing a new and coherent account of causal interactions between the biological, the psychological and social.
