Principles of Bioenergetics


Book Description

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.







Membrane Bioenergetics


Book Description

Membrane bioenergetics is one of the most rapidly growing areas within physico-chemical biology. Main aspects treated in this book include energy conservation and utilization by membrane-linked molecular mechanisms such as intracellular respiration, photosynthesis, transport phenomena, rotation of bacterial flagella, and the regulation of heat production.




Molecular Mechanisms in Bioenergetics


Book Description

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.




Mechanisms of Primary Energy Transduction in Biology


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.




Stress Biology of Cyanobacteria


Book Description

A significant component of many different ecosystems, cyanobacteria occupy almost every niche of the earth, including fresh and salt waters, rice fields, hot springs, arid deserts, and polar regions. Cyanobacteria, along with algae, produce nearly half the global oxygen, making assessment of their ecophysiologies important for understanding climate impacts and potential remediation. Stress Biology of Cyanobacteria: Molecular Mechanisms to Cellular Responses is a compilation of holistic responses of cyanobacteria, ranging from ecological and physiological to the modern aspects of their molecular biology, genomics, and biochemistry. Covering almost every aspect of cyanobacterial stress biology, this book is divided into two parts: Bioenergetics and Molecular Mechanisms of Stress Tolerance and Cellular Responses and Ecophysiology. The first few chapters focus on the molecular bioenergetics of photosynthesis and respiration in cyanobacteria, and provide a clear perspective on different stress tolerance mechanisms. Part I also covers the effect of specific stresses—including heavy metal, high and low temperature, salt, osmotic, and UV-B stress—on a wide range of vital physiological, biochemical, and molecular processes of cyanobacteria. Part II describes mechanisms of symbiosis, stress-induced bioproducts, and the role of environmental factors on nitrogen fixation, which along with photosynthesis is a major contributor to the current geochemical status of the planet. The text also covers mutation and cyanobacterial adaptation, and the most widely studied cyanotoxin, microcystin, which has effects on both human and animal health. With contributions from experts around the world, representing the global importance of cyanobacteria, this book provides a broad compilation of research that deals with cyanobacterial stress responses in both controlled laboratory conditions as well as in their natural environment.




Cells: Molecules and Mechanisms


Book Description

"Yet another cell and molecular biology book? At the very least, you would think that if I was going to write a textbook, I should write one in an area that really needs one instead of a subject that already has multiple excellent and definitive books. So, why write this book, then? First, it's a course that I have enjoyed teaching for many years, so I am very familiar with what a student really needs to take away from this class within the time constraints of a semester. Second, because it is a course that many students take, there is a greater opportunity to make an impact on more students' pocketbooks than if I were to start off writing a book for a highly specialized upper- level course. And finally, it was fun to research and write, and can be revised easily for inclusion as part of our next textbook, High School Biology."--Open Textbook Library.

Bacterial Energetics


Book Description

Bacterial Energetics deals with bacterial energetics and the molecular basis of how ions move between and within energy-transducing molecules. Topics covered range from respiration-driven proton pumps and primary sodium pumps to light-driven primary ionic pumps, bacterial transport ATPases, and bacterial photosynthesis. Sodium-coupled cotransport and ion-exchange systems in prokaryotes are also considered. This volume is comprised of 17 chapters and begins with an analysis of the pumps and processes that establish electrochemical ion gradients across bacterial membranes, followed by a discussion on the major types of bioenergetic work that utilize these gradients. The energetics of periplasmic transport systems, chemolithotrophs, methanogens, and protein insertion and translocation into or across membranes are also examined, along with bioenergetics in extreme environments such as high-pressure and high-temperature environments; energetic problems of bacterial fermentations; energetics of bacterial motility; and energetics of the bacterial phosphotransferase system in sugar transport and the regulation of carbon metabolism. This book should be of interest to molecular biologists and biochemists.
