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.
