Mitochondria and Anaerobic Energy Metabolism in Eukaryotes


Book Description

Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.




Microbiology


Book Description

"Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology's art program enhances students' understanding of concepts through clear and effective illustrations, diagrams, and photographs. Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology."--BC Campus website.

The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology for AP® Courses was designed to meet and exceed the requirements of the College Board’s AP® Biology framework while allowing significant flexibility for instructors. Each section of the book includes an introduction based on the AP® curriculum and includes rich features that engage students in scientific practice and AP® test preparation; it also highlights careers and research opportunities in biological sciences.




Searching for a Mechanism


Book Description

Traces the history of cell bioenergetics from the early notions of science in the Enlightenment through to the end of the twentieth century.




A History of Biochemistry


Book Description




Mitonuclear Ecology


Book Description

This novel text provides a concise synthesis of how the interactions between mitochondrial and nuclear genes have played a major role in shaping the ecology and evolution of eukaryotes. The foundation for this new focus on mitonuclear interactions originated from research in biochemistry and cell biology laboratories, although the broader ecological and evolutionary implications have yet to be fully explored. The imperative for mitonuclear coadaptation is proposed to be a major selective force in the evolution of sexual reproduction and two mating types in eukaryotes, in the formation of species, in the evolution of ornaments and sexual selection, in the process of adaptation, and in the evolution of senescence. The book highlights the importance of mitonuclear coadaptation to the evolution of complex life and champions mitonuclear ecology as an important subdiscipline in ecology and evolution.




The Wine-Dark Sea Within


Book Description

A revisionist history of medicine, in which blood plays the starring role Inspired by Homer’s description of the ebb and flow of the “wine dark sea,” the ancient Greeks conceived a back-and-forth movement of blood. That false notion, perpetuated by the influential Roman physician Galen, prevailed for fifteen hundred years until William Harvey proved that blood circulates: the heart pumps blood in one direction through the arteries and it returns through the veins. Harvey’s discovery revolutionized the life sciences by making possible an entirely new quantitative understanding of the cardiovascular system, a way of thinking on which many of our lifesaving medical interventions today depend. In The Wine-Dark Sea Within, cardiologist Dhun Sethna argues that Harvey’s revelation inaugurated modern medicine and paved the way for groundbreaking advances from intravenous therapy, cardiac imaging, and stent insertions to bypass surgery, dialysis, and heart-lung machines. Weaving together three thousand years of global history, following bitter feuds and epic alliances, tragic failures and extraordinary advancements, this is a provocative history by a fresh voice in popular science.
