Book Description
This book deals with energetics of transport processes, largely expressed in terms of the thermodynamics of irreversible pro cesses. Since at the present time too little is known about the molecular mechanism of transport, the present treatment is based largely on hypothetical models. Care has been taken, however, to define the crucial features of these models as generally as pos sible, so that the equations do not depend too much on hypotheti cal details. Accordingly, most equations, though developed on the basis of a mobile carrier (ferryboat) model, should apply equally to a conformational model, with an appropriate reinterpretation of the symbols. To better elucidate the essentials, the models are greatly simplified by special assumptions. Maximally, only two flows are assumed to be present in each model at one time: e. g. , two solute flows, the flow of solvent and of one solute, the flow of solvent and of heat. The simplifying assumptions may often be unreal. Hence the equations should not be applied un critically to actual mechanisms. They may at best serve as a ba sis on which the more appropriate equations may be developed. The book is not designed to give a complete kinetic analysis of the transport processes described. The kinetic equations are kept to the minimum required to describe the model concerned and to relate it to the corresponding thermodynamic equations. The in tention is to stress the close relationship between bioosmotic (transport) and biochemical processes in metabolism.

Book Description
The material of this volume was originally planned to be incorporated in the preceding monograph Mechanics and Energetics of Biological Transport. A separate and coherent treatment ofthe variety of bioelectrical phenomena was considered preferable, mainly for didactic reasons. Usually, the biologist has to gather the principles of bioelectricity he needs from different sources and on different levels. The present book intends to provide these principles in a more uniform context and in a form adjusted to the problems of a biol ogist, rather than of a physicist or electrical engineer. The main emphasis is put on the molecular aspect by relating the bioelectrical phenomena, such as the membrane diffusion potentials, pump potentials, or redox potentials, to the properties of the membrane concerned, and, as far as pOSSible, to specific steps of transport and metabolism of ions and nonelectrolytes. Little space is devoted to the familiar and widely used representation of bioelectrical phe nomena in terms of electrical networks, of equivalent circuits with batteries, resistances, capacities etc. In order to elucidate the basic principles, the formal treatment is kept as simple as pOSSible, using highly Simplified models, based on biological systems. The corresponding equations are derived in two ways: kinetically, i. e. in terms of the Law of Mass Action, as well as energetically, i. e. , in terms of Nonequilibrium Thermodynamics.

Book Description
Focus, Organization, and Content This book, like the first edition, deals with the mass transport processes that take place in living systems, with a focus on the normal behavior of eukaryotic cells and the - ganisms they constitute, in their normal physiological environment. As a consequence of this focus, the structure and content of the book differ from those of traditional transport texts. We do not start with the engineering principles of mass transport (which are well presented elsewhere) and then seek biological applications of these principles; rather, we begin with the biological processes themselves, and then - velop the models and analytical tools that are needed to describe them. This approach has several consequences. First of all, it drives the content of the text in a direction distinctively different from conventional transport texts. This is - cause the tools and models needed to describe complex biological processes are often different from those employed to describe more well-characterized inanimate systems. Many biological processes must still be described phenomenologically, using me- odologies like nonequilibrium thermodynamics. Simple electrical analogs employing a paucity of parameters can be more useful for characterization and prediction than complex theories based on the behavior of more well-defined systems on a laboratory bench. By allowing the biology to drive the choice of analysis tools and models, the latter are consistently presented in the context of real biological systems, and analysis and biology are interwoven throughout.

Book Description
The book offers a unified description of mass transport, including transmembrane transport both for chemical and biological membranes, and kinetics of chemical reactions. The innovative description is based on a combination of classical mechanics and Einstein’s mobility of molecules in Brownian movement. It is simpler but more powerful than the traditional and rather formal linear thermodynamics approach. This book is the first ever to use modified ideas familiar from classical mechanics, such as energy and force per mol, for a systematic description of equilibrium and nonequilibrium physicochemical processes. The description combines three fundamental components: Einstein’s mobility for Brownian movement, the equation for chemical transport rates in fluids, and an equation for physico-chemical potential. In combination with Newton’s laws and Gibbs’ laws of equilibrium thermodynamics, these three fundamental components naturally lead to nearly all major mass transport equations. These equations are presented in a single unifying Table of Mass Transport and Equilibrium Laws. Presents an innovative and unifying physico-chemical approach Provides insight into the fundamentals of mass transport Covers biological and synthetic membranes

Book Description
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.

Book Description
Describes the physico-chemical laws underlying various kinds of motion in biological systems, with particular emphasis on the mathematics involved. Each chapter covers one type of biological motion, employing mathematics no more advanced than elementary calculus. Explained are biological phenomena such as osmotic pressure, frictional resistance, diffusion, motion in electrical fields, potentials at interfaces, transport across membranes, and entropy-driven processes. Also covered are viscosity, conversion of chemical to mechanical energy, and critical concentrations.
