Bioenergetics

Bioenergetics deals with the very first energy transformation steps performed by living cells. Increased dissipation is the primary effect of processing external energy packages. Enzyme-supported charge separation is the minor but essential outcome for maintaining life. This book explores the usefulness of dissecting the entropy production of enzymes involved in cellular defenses, fermentation, respiration, and photosynthesis, assuming that tightly regulated dissipation is the hallmark of life. Researchers, educators, and students of life sciences can find in this text many examples of how we can use the interdisciplinary approach to study cells' virtuoso ability to connect the microscopic to the macroscopic world. Each chapter is a self-contained unit with a glossary and selected references for further reading.

Cellular life depends upon energy storage, transformation, utilization, and exchange in order to optimally function and to stay-off death. The over 200-year-old study of how cells transform biological fuels into usable energy, a process broadly known as bioenergetics, has produced celebrated traditions in explaining origins of life, metabolism, ecological adaptation, homeostasis, biosynthesis, aging, disease, and numerous other life processes. InTech's edited volume, Bioenergetics, brings together some of these traditions for readers through a collection of chapters written by international authorities. Novice and expert will find this book bridges scientific revolutions in organismic biology, membrane physiology, and molecular biology to advance the discipline of bioenergetics toward solving contemporary and future problems in metabolic diseases, life transitions and longevity, and performance optimization.

Bioenergetics, the topic of volume 5 of this Series, is concerned with the energetics, the kinetics, and the mechanisms of energy conversion in biological systems. This phenomenon can be investigated on diffe rent levels of complexity. On a global level the role of biological pro cesses for the steady state of our enviroment is considered. At the physiological level, the relation between energy input and the physiolo gical state of an organism is of interest, while at the cellular level the biochemical pathways for degradation and synthesis of all relevant substrates is investigated. At present the majority of bioenergetic stu dies pertain to the molecular level. The processes in a cell are cataly zed by a large number of proteins called enzymes. The enzymes in volved in energy transduction can be considered as molecular ma chines which transform energy from one form into another, or transfer energy from one process to another. Living systems operate far from equilibrium and are open in the ther modynamic sense, i. e. they exchange energy and matter with the sur roundings. Chapter 1 presents the principles of non equilibrium thermo dynamics applied to biological systems. About 0. 05% of the energy from the sunlight which reaches the surface of the earth is used by plants and algae as well as some bacteria to synthesize organic com pounds, and thus supplies all organisms with the energy necessary for life.

Clinical Bioenergetics: From Pathophysiology to Clinical Translation provides recent developments surrounding the etiology and pathophysiology of inherited and acquired energy-delated disorders. Across 40 chapters, world leaders in bioenergetics and mitochondrial medicine discuss novel methodologies designed to identify deficiencies in cellular bioenergetics, as well as the safety and efficacy of emerging management strategies to address poor cellular bioenergetics. Topics discussed include the omics landscape of impaired mitochondrial bioenergetics, hormones, tissue bioenergetics and metabolism in humans. Disease-specific case studies, modes of analysis in clinical bioenergetics, and therapeutic opportunities for impaired bioenergetics, addressing both known treatment pathways and future directions for research, are discussed in-depth. Diseases and Disorders examined include brain injury, chronic fatigue syndrome, psychiatric disorders, pulmonary fibrosis, neurodegenerative disorders, heart failure, chronic kidney disease, obesity, and insulin resistance, among others. - Provides a thorough discussion of foundational aspects of bioenergetics and disease, modes of analysis, and treatments for impaired bioenergetics - Discusses the role of bioenergetics and treatment pathways in brain injury, chronic fatigue syndrome, psychiatric disorders, pulmonary fibrosis, neurodegenerative disorders, heart failure, chronic kidney disease, obesity, and insulin resistance, among other diseases and disorders - Features chapter contributions from international leaders in translational bioenergetics research and clinical practice

Revised and updated to include the many developments that have taken place in bioenergetics, this text covers the structures of key membrane proteins involved in bioenergetics and mitochondrial physiology.

This text applies bioenergetics to aquatic animals and explores its role in aquaculture and fisheries science. It seeks to provide a compact account of bioenergetics in aquaculture and clarify problems encountered in the areas of fisheries and

Current Topics in Bioenergetics, Volume 15: Structure, Biogenesis, and Assembly of Energy Transducing Enzyme Systems presents the reaction mechanisms involved in membrane-associated energy transducing processes at the molecular level. This book discusses the developments in the energy transducing systems. Organized into 11 chapters, this volume begins with an overview of the composition and structural aspects of the four respiratory chain complexes. This text then discusses the genetic aspects of various energy transducing systems. Other chapters consider the electron transfer chains of chloroplast, mitochondria, and some photosynthetic bacteria, which contain a multiprotein complex with similar functional and structural properties. This book discusses as well the structure and function of multiple and variable amounts of subunits in cytochrome-c oxidase from various organisms. The final chapter deals with the interdisciplinary path of bioenergetics, with the center of gravity moving from chemistry through genetics to physics. This book is a valuable resource for biologists.

"More in-depth than cursory discussions found in exercise physiology texts and more practical and accessible than dedicated bioenergetics texts, Bioenergetics Primer for Exercise Science encompasses all the up-to-date research and information regarding human bioenergetics and energy metabolism. It offers both students and professionals a depth of knowledge that will inform their further study, research, and profession."--Jacket.
