Book Description
General Biophysics, Volume I deals with the theoretical physics underlying biological phenomena and presents some pertinent experimental results. It explores the molecular foundations of biophysics, the thermodynamics of nonequilibrium systems and membrane transport, nerve impulses, and mechanochemical processes. Comprised of five chapters, this volume begins with an overview of molecular biophysics and the concept of molecular recognition, followed by a discussion of the interaction between antibodies and antigens, the primary processes that determine odor reception, and the importance of intercellular interactions in the existence and development of multicellular organisms. The next chapters explain how protein biosynthesis is regulated by molecules and how proteins are biosynthesized in eukaryotic cells, along with the application of thermodynamics to the analysis of biophysical problems and the coupling of chemical reactions near equilibrium. The reader is also introduced to the stability conditions of a steady state, the concept of entropy for an open system, the thermodynamics of the sodium pump, ionic equilibrium between sodium and potassium solutions separated by an active membrane, the conformational properties of membranes, and the general phenomenological theory of facilitated transport and the role of the carriers. The book concludes with a chapter on biological mechanochemical processes and their thermodynamics. This book is a valuable resource for physicists and biophysicists, graduate and postgraduate students having the necessary knowledge of physics, and anyone acquainted with proteins and nucleic acids.

Book Description
Provides a thorough overview of current research with the green alga Chlamydomonas on chloroplast and mitochondrial biogenesis and function, with an emphasis on the assembly and structure-function relationships of the constituents of the photosynthetic apparatus. Contributions emphasize the multidisciplinary nature of current research in photosynthesis, combining molecular genetics, biochemical, biophysical, and physiological approaches. The 36 articles address topics including nuclear genome organization; RNA stability and processing; splicing; translation; protein targeting in the chloroplast; photosystems; pigments; glycerolipids; the ATP synthase; and ferrodoxin and thioredoxin. Further contributions address new measurements methods for photosynthetic activity in vivo; starch biosynthesis; the responses of Chlamydomonas to various stress conditions; nitrogen assimilation; and mitochondrial genetics.

Book Description
"This volume inspires. It certainly will be much appreciated by cell biologists all over the world." Quarterly Review of Biology, March 2009 This book is the eagerly awaited second edition of the best-selling Mitochondria, a book widely acknowledged as the first modern, truly comprehensive authored work on the important, scientifically fundamental topic of the cellular organelles known as mitochondria. This new edition brings readers completely up to date on the many significant findings that have occurred in the eight years since the book was first published. As in that seminal first edition, the second edition tackles the biochemistry, genetics, and pathology of mitochondria in different organisms. The new edition provides thorough updates of all literature concerning this vital organelle, its functions, ongoing research surrounding it, and its importance vis-à-vis a broad range of issues in cellular and molecular biology. The book includes detailed descriptions of current and developing technologies around mitochondrial research and discovery, and highlights subjects that are growing, such as the use of proteomics. This book is an invaluable resource for all geneticists, biologists, and educators in life sciences. It is also of interest for advanced students in genetics and molecular biology.

Book Description
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.

Book Description
Muscle contraction has been the focus of scientific investigation for more than two centuries, and major discoveries have changed the field over the years. Early in the twentieth century, Fenn (1924, 1923) showed that the total energy liberated during a contraction (heat + work) was increased when the muscle was allowed to shorten and perform work. The result implied that chemical reactions during contractions were load-dependent. The observation underlying the “Fenn effect” was taken to a greater extent when Hill (1938) published a pivotal study showing in details the relation between heat production and the amount of muscle shortening, providing investigators with the force-velocity relation for skeletal muscles. Subsequently, two papers paved the way for the current paradigm in the field of muscle contraction. Huxley and Niedergerke (1954), and Huxley and Hanson (1954) showed that the width of the A-bands did not change during muscle stretch or activation. Contraction, previously believed to be caused by shortening of muscle filaments, was associated with sliding of the thick and thin filaments. These studies were followed by the classic paper by Huxley (1957), in which he conceptualized for the first time the cross-bridge theory; filament sliding was driven by the cyclical interactions of myosin heads (cross-bridges) with actin. The original cross-bridge theory has been revised over the years but the basic features have remained mostly intact. It now influences studies performed with molecular motors responsible for tasks as diverse as muscle contraction, cell division and vesicle transport.

Book Description
Exploring current themes in modern computational and membrane protein biophysics, this book presents a comprehensive account of the fundamental principles underlying different methods and techniques used to describe the intriguing mechanisms by which membrane proteins function. The book discusses the experimental approaches employed to study these proteins, with chapters reviewing recent crucial structural advances that have allowed computational biophysicists to discern how these molecular machines work. The book then explores what computational methods are available to researchers and what these have taught us about three key families of membrane proteins: ion channels, transporters and receptors. The book is ideal for researchers in computational chemistry and computational biophysics.
