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.
