This book is concerned with the physical aspects of molecular and electronic tunneling in biological systems, and the extent to which protein structure controls these events. The scope is very broad and this volume could almost be a textbook in biophysics. Both fundamental processes and the extrapolation to physiological events are stressed. The discussion sections are remarkably frank and offer insight into the basic problems confronting physists and chemists as they seek to apply their techniques to biological systems. This book on the physics of biomolecules reflects recent progress in understanding the biological function of the key protein molecules from detailed knowledge of their physics. New and exciting are the glasslike aspects of protein structures and the discussion of proteins as fractals. Other topics dealt with are low-temperature kinetics and reactivity, structure and charge exchange, and charge separation in photosynthetic reaction centers.

Biological and Biochemical Oscillators compiles papers on biochemical and biological oscillators from a theoretical and experimental standpoint. This book discusses the oscillatory behavior, excitability, and propagation phenomena on membranes and membrane-like interfaces; two-dimensional analysis of chemical oscillators; and chemiluminescence in oscillatory oxidation reactions catalyzed. The problems associated with the computer simulation of oscillating systems; mechanism of single-frequency glycolytic oscillations; excitation wave propagation during heart fibrillation; and biochemical cycle of excitation are also elaborated. This compilation likewise covers the physiological rhythms in Saccharomyces cerevisiae populations; integral and indissociable property of eukaryotic gene-action systems; and role of actidione in the temperature jump response of the circadian rhythm in Euglena gracilis. This publication is valuable to biochemists interested in biochemical and biological oscillations.

Tunneling in Biological Systems focuses on the low temperature electron transport that reveals a quantum-mechanical effect called "tunneling. This book discusses the tunneling in physical systems; detection of molecular vibrations with electron tunneling; chemical-rate theory of small-polaron hopping; and experimental approaches to electronic coupling in metal ion redox systems. The Faraday rotation and photoconductivity of photosynthetic structures at microwave frequencies; dynamics of electron transport in macromolecules; and electron transfer reactions in cytochrome oxidase are also elaborated. This text likewise covers the kinetic evidence for electron tunneling in solution; specificity and control in biological systems; molecular tunneling in heme proteins; and ligand binding. This publication is valuable to students and researchers interested in the physics of biological and medical problems.

Probes of Structure and Function of Macromolecules and Membranes, Volume I: Probes and Membrane Function discusses the developments in techniques for the measurement of rapid reactions and detection of enzymatic reactions in simple and complex systems. This book describes the application of the incisive techniques employed for the study of activity-related structural changes in enzymes to functionally related structural changes in membranes. The structural changes initiated in response to energy coupling and ion movements in mitochondria and axons are also elaborated. This publication covers the basic mechanisms by which structural changes can participate in energy coupling at the redox level of the hemoproteins that leads to the evaluation of the function of ubiquinone and cytochrome b in energy coupling. The function of factors that couple electron transport and energy conservation is likewise considered. This volume is a good reference for students and researchers conducting work on the structure and function of macromolecules and membranes.

Control of Energy Metabolism: A Colloquium of the Johnson Research Foundation focuses on the processes, reactions, and approaches involved in the control of energy metabolism. The selection first offers information on the respiratory chain as a model for metabolic control in multi-enzyme systems, dynamics and control in cellular reactions, and computer-based analysis of biochemical data. The text then explores purification and properties of rabbit skeletal muscle phosphofructokinase; multiple forms of heart phosphofructokinase; and mechanisms of inhibition and activation of phosphofructokinase in Novikoff ascites tumor cells. Discussions focus on the properties of purified phosphofructokinase; effect of heart extracts on reactivation of phosphofructokinase; active and inactive forms of phosphofructokinase; and effect of hexose phosphate and adenylic nucleotides on reactivation of phosphofructokinase. The manuscript takes a look at enzyme and metabolite profiles; coordinated stimulation of hexokinase and phosphofructokinase by phosphate in a reconstituted system of glycolysis; control of hexokinase in ascites tumor glycolysis; and cation flux across the mitochondrial membrane as a possible pacemaker of tissue metabolism. The selection is a vital reference for biochemists and researchers interested in the control of energy metabolism.

Energy-Linked Functions of Mitochondria presents the developments in the area of energy-linked functions of mitochondria. This book covers three general topics, namely, the generation, the transfer, and the utilization of reducing power. Organized into three parts encompassing 16 chapters, this book begins with an overview of the various steps involved in the combined electron and energy transfer reactions that lead to the generation of high-energy intermediates. This text then examines the effect of atracytloside and oligomycin on oxidative phosphorylation in submitochondrial particles. Other chapters consider a detailed review of the succinate-linked DPN reduction in submitochondrial particles. This book discusses as well the concept of energy-linked reversal of electron transport from reduced cytrochome c to pyridine nucleotide. The final chapter deals with the transient activation of respiration of tightly coupled mitochondria by adding low concentrations of calcium. This book is a valuable resource for scientists who are interested in energy-linked processes in mitochondria.
