Book Description
The problem of electron transfer phosphorylation was first formu lated in 1939 by Belitser and Tsibakova I who introduced the "P: 0" criterion and showed that this ratio is more than 1. The authors noted that such a high value of the phosphorylation coefficient suggests a fundamental difference in the mechanisms of A TP formation coupled with respiration, and glycolysis, since in the latter case, the amount of the ATP synthesized is equal to that of the substrate utilized. A lot of hypothetical schemes were put forward to explain the nature of coupling between electron transfer and phosphorylation, but none of them solved the problem. Only quite recently, one hypo thetical scheme of energy coupling, viz. Mitchell's chemiosmotic concept, 2.3 was supported by experimental data which allow us to prefer it to alternative possibilities. In this paper, I shall try to substantiate the statement that oxidation and phosphorylation can be coupled via a membrane potential as was postulated by Mitchell.

Book Description
Energy Transduction in Biological Membranes was primarily designed for graduate courses in bioenergetics. Not only does it discuss basic principles and concepts central to modern membrane biochemistry, biophysics and molecular biology, but also (1) the components and pathways for electron transport and hydrogen ion translocation, and (2) the utilization of electrochemical ion gradients. The book is unique in presenting a comparative treatment of respiratory and photosynthetic energy transduction, and in using protein sequence data coupled with physical concepts to discuss the mechanisms of energy transducing proteins.

Book Description
This book describes the events of primary energy transduction in life processes. Life as we know it depends on pumping protons across membranes. New tools to study the protein complexes involved has led to recent intensified progress in the field. Primary Energy Transduction in Biology focusses on recent structural results and new biophysical insights. These have been made possible by recent advances in high-resolution protein structures, in physical techniques to study reactions in real time, and in computational methods to study and refine both structures and their dynamics. Written and edited by leading experts, chapters discuss the latest key questions in cell respiration, photosynthesis, bioenergetics, proton transfer, electron transfer and membrane transport. Biochemists, biophysicists and chemical biologists will find this book an essential resource for a complete understanding of the molecular machines of bioenergetics.

Book Description
Light Transducing Membranes: Structure, Function, and Evolution covers the proceedings of a joint United States-Australia conference held in Honolulu, Hawaii on December 1977. Organized into four parts encompassing 19 chapters, the book focuses on structural, functional, and evolutionary aspects of light energy transduction by membranes. The first part of the book explores the problems of how membrane-related biomolecules could have evolved prior to the origin of life, how amphiphiles might have become organized in lipid bilayer structures, and what mechanisms may have been available for light energy transduction. The mechanisms by which ions, lipids, and proteins interact in membrane systems are described in the next part of the book. Some chapters in the third part of the book cover the analysis of several bacterial membranes as reconstituted, light transducing systems, providing a new tool for investigating basic mechanisms. Relevant aspects of mitochondrial energy transduction are also covered. Finally, the last part presents mechanism analysis by which intact bacteria and chloroplasts interact with light energy, which represent the end product of several billion of years of evolution. Biological evolutionists, biologists, researchers, teachers, and students who are interested in various aspects of light transducing membranes will greatly benefit from this book.
