Available in PDF, EPUB and Kindle. Book excerpt: Almost twenty years ago DE DuvE discovered the existence in rat liver cells of a novel class of subcellular structures which he termed lysosomes. As the lysosomes are the seat of various hydrolytic enzymes this discovery greatly stimulated the interest in cellular digestive processes. It is now recognized that compartmentation of hydrolases is an outstanding example of the dependence of metabolic functions on cell structure. The important role of lytic processes in plant metabolism made it interesting to correlate the facts on the various phenomena and present them from the point of view of cellular compartmentation. It is not intended to survey in extenso the litera ture on the various aspects of localization and function of hydrolases in plant cells as this would be an impossible task. The aim of this monograph is to emphasize the significance of hydrolase compartmentation rather than to strive for complete coverage of work on hydrolases in which other viewpoints have been considered. I thank Miss SONIA TURLER for her great help with the manuscript. I also wish to acknowledge the assistance given by Dr. ELSA HAUSERMANN, Mrs. DORLI FURRER, and Mrs. SILVIA STUNZI. Moreover, I am indebted to my collaborators and particularly to my colleague Dr. A. WIEMKEN for frequent and stimulating discussions on the subject. Zurich (Switzerland), February 1975 PH.

This book was released on 2013-06-29 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: THIS BOOK HAS BEEN WRITTEN BECAUSE WE FEEL THAT THERE IS A NEED FOR AN up-to-date compact book on cell organelles that transmits the excitement and challenge of modern subcellular biology. We hope that the book will be interesting and useful to students of the biological sciences and medicine, and to those in the teaching professions who do not have ready access to research papers. Since space is at a premium, we have denied ourselves the luxury of a philosophical discussion of the problems of defining organelles. Rather we have chosen to include all those intracellular structures which have limiting membranes and definable compartments. The separate chapters consider nuclei, plastids, mitochondria, microbodies, endoplasmic and sarcoplasmic reticulum; Golgi bodies, lysosomes and various secretory vesicles, including chromaffin granules and synaptic vesicles. Nucleoli, ribosomes, and centrioles are included in the chapter on nuclei. New and exciting informatioIi about all these structures has emerged in recent years-for example; the nUcleosome, interrupted genes, signal sequences on proteins destined. for the bioenergetic organelles, mapping and sequencing of organelle genes, and consolidation of chemiosmosis as a unifying principle in energy transduction. We have outlined as many of these developments as possible and pointed out some areas of controversy. The literature on subcellular biology is so extensive that it would have been easier to have written a separate book on each organelle.

Available in PDF, EPUB and Kindle. Book excerpt: In the last ten years there has been a considerable increase of interest on the notion of the minimal cell. With this term we usually mean a cell-like structure containing the minimal and sufficient number of components to be defined as alive, or at least capable of displaying some of the fundamental functions of a living cell. In fact, when we look at extant living cells we realize that thousands of molecules are organized spatially and functionally in order to realize what we call cellular life. This fact elicits the question whether such huge complexity is a necessary condition for life, or a simpler molecular system can also be defined as alive. Obviously, the concept of minimal cell encompasses entire families of cells, from totally synthetic cells, to semi-synthetic ones, to primitive cell models, to simple biomimetic cellular systems. Typically, in the experimental approach to the construction of minimal the main ingredient is the compartment. Lipid vesicles (liposomes) are used to host simple and complex molecular transformations, from single or multiple enzymic reactions, to polymerase chain reactions, to gene expression. Today this research is seen as part of the broader scenario of synthetic biology but it is rooted in origins of life studies, because the construction of a minimal cell might provide biophysical insights into the origins of primitive cells, and the emergence of life on earth. The volume provides an overview of physical, biochemical and functional studies on minimal cells, with emphasis to experimental approaches. 15 International experts report on their innovative contributions to the construction of minimal cells.

Download or read book Size Limits of Very Small Microorganisms written by National Research Council and published by National Academies Press. This book was released on 1999-10-13 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: How small can a free-living organism be? On the surface, this question is straightforward-in principle, the smallest cells can be identified and measured. But understanding what factors determine this lower limit, and addressing the host of other questions that follow on from this knowledge, require a fundamental understanding of the chemistry and ecology of cellular life. The recent report of evidence for life in a martian meteorite and the prospect of searching for biological signatures in intelligently chosen samples from Mars and elsewhere bring a new immediacy to such questions. How do we recognize the morphological or chemical remnants of life in rocks deposited 4 billion years ago on another planet? Are the empirical limits on cell size identified by observation on Earth applicable to life wherever it may occur, or is minimum size a function of the particular chemistry of an individual planetary surface? These questions formed the focus of a workshop on the size limits of very small organisms, organized by the Steering .Group for the Workshop on Size Limits of Very Small Microorganisms and held on October 22 and 23, 1998. Eighteen invited panelists, representing fields ranging from cell biology and molecular genetics to paleontology and mineralogy, joined with an almost equal number of other participants in a wide-ranging exploration of minimum cell size and the challenge of interpreting micro- and nano-scale features of sedimentary rocks found on Earth or elsewhere in the solar system. This document contains the proceedings of that workshop. It includes position papers presented by the individual panelists, arranged by panel, along with a summary, for each of the four sessions, of extensive roundtable discussions that involved the panelists as well as other workshop participants.

Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book Biocommunication of Archaea written by Guenther Witzany and published by Springer. This book was released on 2017-09-27 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaea represent a third domain of life with unique properties not found in the other domains. Archaea actively compete for environmental resources. They perceive themselves and can distinguish between ‘self’ and ‘non-self’. They process and evaluate available information and then modify their behaviour accordingly. They assess their surroundings, estimate how much energy they need for particular goals, and then realize the optimum variant. These highly diverse competences show us that this is possible owing to sign(aling)- mediated communication processes within archaeal cells (intra-organismic), between the same, related and different archaeal species (interorganismic), and between archaea and nonarchaeal organisms (transorganismic). This is crucial in coordinating growth and development, shape and dynamics. Such communication must function both on the local level and between widely separated colony parts. This allows archaea to coordinate appropriate response behaviors in a differentiated manner to their current developmental status and physiological influences. This book will orientate further investigations on how archaeal ecosphere inhabitants communicate with each other to coordinate their behavioral patterns and whats the role of viruses in this highly dynamic interactional networks.

Download or read book Cell Physiology written by Henry Tedeschi and published by Elsevier. This book was released on 2012-12-02 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cell Physiology: Molecular Dynamics focuses on the molecular aspects of cell physiology. It analyzes the functional and structural organization of the cell as a unit of inheritance and a biochemical transducer; the mechanisms of genetic transmission; the transcription and translation of the genetic message; the capture of energy in oxidative phosphorylation and photosynthesis; and the principle of semi-conservation in DNA duplication. Experiments illustrate the basic principles described in this book. Organized into three sections encompassing 19 chapters, this volume begins with an overview of the cell as a system of compartments, and the possible functional significance of compartmentation. It then turns to a discussion of some of the processes involved in the functioning of the cell, the genetic control of cell function, the replication of DNA, and extrachromosomal inheritance. The reader is also introduced to interactions between organelles and the nucleus; differentiation and control of protein synthesis; the role of enzymes in the regulation of metabolism; and control of macromolecules in bacteria and in some mammalian tissues. The books also covers oxidative phosphorylation and mitochondrial organization; transport and permeability of the cell membrane; the role of specialized cells in the excitation and conduction of signals; and the molecular basis of mechanochemical coupling. This book is a valuable resource for undergraduate students with a basic knowledge of the biochemical and genetic approaches to biology.
