Download or read book Organized Multienzyme Systems Catalytic Properties written by G. Rickey Welch and published by Elsevier. This book was released on 2012-12-02 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organized Multienzyme Systems: Catalytic Properties describes the kinetic and catalytic properties of organized enzyme systems. This book is composed of nine chapters that specifically cover both immobilized and naturally occurring systems. The first two chapters examine the nature and function of enzyme organization in the mitochondrion, as well as the structural/functional coupling of the components in energy-transducing membrane systems. These topics are followed by discussions on ""dynamic compartmentation"" in soluble multienzyme systems; the allosteric enzyme systems; and allosterism in reversibly adsorptive enzyme systems. Other chapters explore model studies with specific immobilized multienzyme sequences, as regards the analysis of microenvironmental effects, and the mathematical exposition on the kinetic analysis of multienzyme systems in homogeneous solution. The last chapters present some theoretical and experimental studies on the behavior of immobilized systems. These chapters also provide a speculative integrative view of the kind of functional coherence that may be operative in organized states in vivo. This book is of great value to cell biologists, biochemists, and enzyme scientists and researchers.

Available in PDF, EPUB and Kindle. Book excerpt: Current Topics in Cellular Regulation: Volume 29 is a collection of papers that deals with dynamic macromolecular interactions, ligand binding, multi-enzyme complex formation, the regulation of fatty acid uptake, and synthesis in mammary or adipose tissues. Other papers explain the functional relationships of guanosine triphosphate binding proteins, the glycogen storage disease, the regulation of the pentose phosphate pathway in the brain, as well as the regulation of carotenoid biosynthesis. One paper discusses the dissociable enzyme complexes stabilized by weak interactions, particularly on the interaction of cytosolic enzymes with the contractile apparatus, with membranes, or with functionally related enzymes. Another paper investigates the mechanism of acute regulation, in mammary epithelial cells, of the processes which collaborate to supply fatty acids for esterification to form glycerolipids (which is predominantly triacylglycerol). Glycerolipids comprise mostly the total lipid content of the secretory product of those cells—mammalian milk. The paper notes that a counter-regulatory hormone collaborating with insulin in the regulation of lipid metabolism in the lactating mammary cell, does not act via cyclic AMP. The collection can prove beneficial for biochemists, micro-biologists, bio-physicists, cellular researchers, and academicians involved in the study of cellular biology or physiology.

Download or read book Emergent Collective Properties Networks and Information in Biology written by J. Ricard and published by Elsevier. This book was released on 2006-02-10 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of network as a mathematical description of a set of states, or events, linked according to a certain topology has been developed recently and has led to a novel approach of real world. This approach is no doubt important in the field of biology. In fact biological systems can be considered networks. Thus, for instance, an enzyme-catalysed reaction is a network that links, according to a certain topology, the various states of the protein and of its complexes with the substrates and products of the chemical reaction. Connections between neurons, social relations in animal and human populations are also examples of networks. Hence there is little doubt that the concept of network transgresses the boundaries between traditional scientific disciplines. This book is aimed at discussing in physical terms these exciting new topics on simple protein model lattices, supramolecular protein edifices, multienzyme and gene networks. *Physical and mathematical approach of biological phenomena. *Offers biochemists and biologists the mathematical background required to understand the text. *Associates in the same general formulation, the ideas of communication of a message and organization of a system. *Provides a clear-cut definition and mathematical expression of the concepts of reduction, integration, emergence and complexity that were so far time-honoured and vague
Download or read book Biological Complexity and the Dynamics of Life Processes written by J. Ricard and published by Elsevier. This book was released on 1999-11-01 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to show how supramolecular complexity of cell organization can dramatically alter the functions of individual macromolecules within a cell. The emergence of new functions which appear as a consequence of supramolecular complexity, is explained in terms of physical chemistry. The book is interdisciplinary, at the border between cell biochemistry, physics and physical chemistry. This interdisciplinarity does not result in the use of physical techniques but from the use of physical concepts to study biological problems. In the domain of complexity studies, most works are purely theoretical or based on computer simulation. The present book is partly theoretical, partly experimental and theory is always based on experimental results. Moreover, the book encompasses in a unified manner the dynamic aspects of many different biological fields ranging from dynamics to pattern emergence in a young embryo. The volume puts emphasis on dynamic physical studies of biological events. It also develops, in a unified perspective, this new interdisciplinary approach of various important problems of cell biology and chemistry, ranging from enzyme dynamics to pattern formation during embryo development, thus paving the way to what may become a central issue of future biology.

Download or read book Microcompartmentation written by D.P. Jones and published by CRC Press. This book was released on 2018-01-18 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microcompartmentation refers to nonhomogeneous distribution of solutes in compartments of cells or associated structures without intervening membranal barriers. Such variations in concentration of ions, metabolites, intracellular messengers, and nutrients can introduce significant heterogeneity in subcellular function and regulation. The current focus on biological examples of microcompartmentation provides ample evidence for its importance and the role of physical structure in determining local chemical environments. The examples present in the different chapters include microcompartmentation of Ca2+,H+,ATP. ADP, O2, glycolytic intermediates, fatty acids, amino acids, and nucleic acid precursors. In reviewing these systems, the authors provide a useful resource for experimental approaches to study microcompartmentation and provide the basis for future studies of its role in regulation of cell functions.
Download or read book Molecular and Biological Physics of Living Systems written by R.K. Mishra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The living organisms and systems possess extraordinary properties of programmed development, differentiation, growth, response, movement, duplication of key molecules and in m any cases higher mental functions. But the organisms are physical objects so they must follow laws of physics yet they do not seem to obey them. Physicists cannot easily persuade themselves to accept this as finally true. Non-living objects are governed by these laws of physics and they can explain these properties. However, in the living systems too phenomena encountered like coupled non-linear interactions, manybody effects, cooperativity, coherence, phase transitions, reversible metastable states are being understood better with the aid of powerful theoretical and experimental techniques and hope is raised that these may let us understand the mysteriousness of life. Contributors to this volume are a small fraction of rapidly growing scientific opinion that these aspects of living bodies are to be expected in a hitherto inadequately suspected state of matter which is in the main directed by these physical properties pushed almost to limit. This state of matter, the living matter, deserves to be called The Living State. Mishra proposes that given hydrogenic orbitals, atoms showing easy hybridisability and multiple valances, molecules with low-lying electronic levels, "loosestructure", and a metabolic pump in thermodynamically open system, various fundamental properties of living state can emerge automatically. Structurally these are all known to be present.

Download or read book Organism and the Origins of Self written by A.I. Tauber and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: "De la vaporisation et de la centralisation du Moi. Tout est la. " Charles Baudelaire (journal entry) This anthology is my visit to Oz. On sabbatical in 1988, I chose to reeducate myself in general biology, first broadening my erudition as an immunologist, and then extending that horizon into evolutionary biology and embryology. I was particularly attracted to reflections on the nature of the self as an organ ismic concept. I went in search of reorientation as a confused physician scientist, and came back with this book. Baum's Wizard of Oz presented opportunities for growth, and herein lies the purpose of this volume: in providing updated statements concerning the nature of the organism from both scientific and metaphysical perspectives, we might ponder the philo sophical basis of our research in the hope of gaining insight into our endeavor, not to mention the possibility of its enrichment; it is this contem plative view of our research which offers a unique dimension to this anthology. To that end, the project follows my idiosyncratic prejudices. The anthology derives in large measure from the symposium, "Organism and the Origin of Self' held at Boston University, April 3-4, 1990, under the auspices of the Boston University Center for the Philosophy and History of Science, with generous support of Robert Cohen and Jon Westling, and the organizational skills of Deborah Wilkes. The Symposium presented three ver sions of the Self from the vantages of embryology, evolution and medicine.

This book was released on 2009-07-24 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hopefully, this book will be taken off of the shelf frequently to be studied carefully over many years. More than 40 researchers were involved in this project, which examines respiration, circulation, and metabolism from ?sh to the land vertebrates, including human beings. A breathable and stable atmosphere ?rst appeared about 500 million years ago. Oxygen levels are not stable in aquatic environments and exclusively water-breathing ?sh must still cope with the ever-changing levels of O 2 and with large temperature changes. This is re?ected in their sophisticated count- current systems, with high O extraction and internal and external O receptors. 2 2 The conquest for the terrestrial environment took place in the late Devonian period (355–359 million years ago), and recent discoveries portray the gradual transitional evolution of land vertebrates. The oxygen-rich and relatively stable atmospheric conditionsimpliedthatoxygen-sensingmechanismswererelativelysimpleandl- gain compared with acid–base regulation. Recently, physiology has expanded into related ?elds such as biochemistry, molecular biology, morphology and anatomy. In the light of the work in these ?elds, the introduction of DNA-based cladograms, which can be used to evaluate the likelihood of land vertebrates and lung?sh as a sister group, could explain why their cardio-respiratory control systems are similar. The diffusing capacity of a duck lung is 40 times higher than that of a toad or lung?sh. Certainly, some animals have evolved to rich high-performance levels.
Download or read book Energy Transfer Dynamics written by Terence William Barrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: On three occasions and at different locations, conferences were held to honor the eightieth birthday of Professor Herbert Frohlich: on the 18th December, 1985, in Liverpool, England; on the 14th February, 1986, in Stuttgart, Germany; and on the 8th March, 1986, on the Palm Coast, Florida. This Festschrift is a compilation of the papers of those conferences. Frohlich's choice of problems, from the earliest days, was couched in the phy sics of intrinsically interacting systems of excitation. One example, in which he set the course of research which is still followed, concerned dielectric breakdown, developed from the 1930's over several decades. The interacting systems are the electrons (receiving energy from an electric field) and lattice atom motion (taking energy from the electrons via "electron-phonon" interaction, hence heat dissipa tion). There is a threshold field above which the latter cannot keep up with the former, and the combined system (electrons plus phonons) "runs away"; that is to say, collectively it switches to a new state.
