A New Look at Mechanisms in Bioenergetics features eight lectures based on the Robbins Lectures given at Pomona College in April 1973. These lectures are based mainly on the author's own laboratory work and are intended for students of biology and biochemistry who want to devote their lives to research. Lecture 1 presents some of the general lessons learned from research in the field of bioenergetics. It also discusses methods for measuring oxidative phosphorylation and the resolution of soluble multienzyme systems. Lecture 2 explains the biochemical approach to the problem of photophosphorylation. Lecture 3 considers the intersection of oxidative phosphorylation and membranology. Lecture 4 discusses the coupling device and its partial reactions. Lecture 5 focuses on the oxidation chain in mitochondria. Lecture 6 discusses the resolution and reconstitution of oxidative phosphorylation. Lecture 7 examines the reconstitution of ion pumps. Finally, Lecture 8 covers oxidation control in glycolysis; the high aerobic glycolysis of tumor cells; ATPases in tumor cells; and the repair of ion pumps in tumor cells.

This book summarises current knowledge of the structure, function,biosynthesis and regulation of energy-transducing enzymes inmitochondria, chloroplasts and bacteria. Each of the twenty chapters is written by top experts in their field, and Prof. Ernster has ensured that the book as a whole gives a well-integrated picture of the present state of knowledge of the field at its different levels and complexities. Since the publication of Bioenergetics edited by Lars Ernster in 1984, (New Comprehensive Biochemistry Vol. 9) the whole field of bioenergetics has undergone a tremendous expansion. Additionally a transition from membrane bioenergetics to molecular bioenergetics has accompanied this expansion - due mainly to the spectacular progress in the field of molecular biology over the past twenty years.Hence this volume, Molecular Mechanisms in Bioenergetics, is certain to be of interest, not only to the specialist in bioenergetics, but also to researchers working in the various fields of biophysics, biochemistry, molecular biology, genetics, cell biology and physiology. Also of interest, this volume contains an historical introduction, including a list of earlier publications relating to the history of bioenergetics.

Bechtel emphasises how mechanisms were discovered by cell biologists and the instruments that made these inquiries possible.

Mechanisms in Bioenergetics covers the proceedings of the eighth conference on ""Mechanisms in Bioenergetics"" held in Pugnochiuso, Italy on May 1-4, 1972. This book is organized into three parts, encompassing 43 chapters that discuss bioenergetics in mitochondria, chloroplasts, chromatophores, and bacterial protoplast membranes. It summarizes the structure and dynamics of energy-transducing membranes, molecular basis of membrane transport, and energy coupling mechanisms. The first part of the book describes various aspects of structure and dynamics of energy transducing membranes. This includes their chemiosmotic coupling, reflection coefficients, structural transformation, redox properties, and circular dichroism studies. This is followed by considerable chapters discussing chemiosmotic theory of transport and metabolism, ion channel phosphorylation paths in cell membrane, and kinetics of metabolite anion uptake in mitochondria. Other topics covered are mitochondrial Ca2+-binding glycoprotein and sucrose-dependent sugar transport across artificial lipid membranes. This book also looks into the enzyme interaction in mitochondrial membrane. It also discusses the relation of hydrogen uptake to electron flow in photosynthetic bacteria and purine nucleotides and fatty acids in energy coupling. The concluding section deals with the mechanisms of energy coupling, including mechanism of respiration-driven proton, role of mitochondrial energy transfer factors, and energy in mitochondrial respiration. The behavior of cytochromes b and c of pigeon heart and in the energized mitochondrial membrane is also described. Finally, this book considers the effect of adenosine-containing compounds competitively inhibiting the mitochondrial transhydrogenase reaction. Researchers and students who are interested in bioenergetics and energy-transducing membranes will benefit from this book.

Bioenergetics is the study of the way biological systems, usually at the molecular level, utilize and convert energy in order to drive the biochemical reactions that constitute life. However, because of its often quantitative basis and the amount of technical jargon, the subject tends to alienate and intimidate students. This beautifully illustrated text has a lucid and logical approach to the subject. The text uses the modern perspective throughout so that the student is given an easily assimilable, logical introduction to the important concepts of the subject, particulary the core concept, the 'chemiosmotic theory'. It has been specifically designed to make information easily accessible by devoting each double-page spread to one topic. Within the spread, a variety of carefully constructed diagrams present information in a concise and innovative manner. The text is further enhanced by a comprehensive guide to additional reading. Original, easily understood combination of visual and written information. 43 double-page speads give a clear and concise introduction to this traditionally difficult subject. The most up to date text available, covering all modern molecular genetic techniques. Competitively priced.

Molecular Mechanisms of Photosynthesis stands as an ideal introduction to this subject. Robert Blankenship, a leading authority in photosynthesis research, offers a modern approach to photosynthesis in this accessible and well-illustrated text. The book provides a concise overview of the basic principles of energy storage and the history of the field, then progresses into more advanced topics such as electron transfer pathways, kinetics, genetic manipulations, and evolution. Throughout, Blankenship includes an interdisciplinary emphasis that makes this book appealing across fields. Leading authority in Photosynthesis and the the President of the International Society of Photosynthesis Research. First authoritative text to enter the market in 10 years. Stresses an interdisciplinary approach, which appeals to all science students. Emphasizes the recent advances in molecular structures and mechanisms. Only text to contain comprehensive coverage of both bacterial and plant photosynthesis. Includes the latest insights and research on structural information, improved spectroscopic techniques as well as advances in biochemical and genetic methods. Presents the most extensive treatment of the Origin and evolution of photosynthesis. Comprehensive appendix, which includes a detailed introduction to the physical basis of photosynthesis, including thermodynamics, kinetics and spectroscopy.

Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.

The First International Workshop on Mechanisms in Cell-Mediated Cytoxicity was held at Carry-Ie-Rouet, France, September 14-16, 1981. The Workshop brought together for the first time leading investiga tors in each of the principal areas of cell-mediated cytotoxicity, as well as experts in the area of complement-mediated cytoxicity. Formal research presentations were held to a minimum, the emphasis being on open discussion of current knowledge about mechanisms of cytoxicity in each of the systems under consideration. The major objectives of the Workshop were 1) to compare and integrate what is known about the mechanism(s) of cytoxicity in each system; 2) to determine whether, on the basis of information in hand, it seems likely that the mechanisms of cytotoxicity in the various systems are the same or are unique; and 3) to stimulate thinking about new approaches to elucidating the fundamental mechanisms by which certain cells are able to kill other cells.
