Organized into six chapters, this volume begins with an overview of the solute transport functions of membrane vesicles from kidney and intestine. This text then examines the specialized calcium transport system of mitochondria from both mechanistic and biological viewpoints. Other chapters consider the energy-transducing mechanisms in bacteria and chromoplast from the standpoint of mechanism. This book discusses as well ionophores and channel formers as powerful tools in the study of membrane function. The final chapter deals with the metabolic link between fundamental cell physiological events, such as hormonal perturbation of metabolism and cell development, on the one hand, and an altered ability of mitochondria to transport Ca2+, on the other. This book is a valuable resource for bioenergeticists, biochemists, biologists, and microbiologists.

Current Topics in Bioenergetics, Volume 2 provides information pertinent to biological energy transduction, both at the molecular level and in systems having a higher degree of organization. This book presents the contractile mechanisms in cilia and flagella. Organized into 10 chapters, this volume begins with an overview of the concept of the photosynthetic unit that has been deeply involved in all models of photosynthesis. This text then discusses the mechanisms of light-induced conformational changes in chloroplasts, mediated by ion transport. Other chapters consider the conservation and utilization of energy derived from the oxidation of organic substrates by plant mitochondria. This book discusses as well the role of ubiquinone, which has undergone the familiar difficulty in establishing whether a redox active component is an obligatory member of the electron transfer in the respiratory chain. The final chapter deals with the steady state potentials found in the inner ear of mammals. This book is a valuable resource for otolaryngologists and scientists.

Current Topics in Bioenergetics, Volume 3 provides information pertinent to the phenomena associated with biological energy transduction at different levels of sophistication. This book discusses the energy-linked processes in mitochondria. Organized into seven chapters, this volume begins with an overview of the core of the mechanism of oxidative phosphorylation. This text then explains the basic features of artificial membranes model system and its usefulness in probing membrane phenomena. Other chapters consider the thermodynamic and kinetic aspects of active transport of ions and attempt to relate photoreception with the subsequent electrophysiological events. This book discusses as well the regulation of respiration by muscular activity and on energy transduction in phototropism and phototaxis. The final chapter deals with the mechanism of phototaxis in microorganisms and explains the phenomenon as a translational response of a freely moving organism to a light stimulus. This book is a valuable resource for biochemists, cell biologists, and physiologists.

Current Topics in Bioenergetics, Volume 4 provides information pertinent to the molecular basis for energy transduction in membranous systems. This book presents the developments of relevant techniques in the field of bioenergetics. Organized into eight chapters, this volume begins with an overview of nonequilibrium and fluorescent probes that deal with relatively unexplored areas. This text then discusses the problem of pathways and mechanisms of energy transformations in the cell. Other chapters consider the transport of ions across the plasma membrane of nearly all living cells, which is a necessary condition for the maintenance of the vital life processes. This book discusses as well that bacterial synthesis offers basic and valuable information of general significance and remarkably stimulating challenges with direct bearing on different aspects of the problem of the basic mechanisms involved in biological electron transport-coupled energy conversion. The final chapter deals with the general models for the transport of sodium and potassium. This book is a valuable resource for biologists and biochemists.
