Cellular Respiration


Book Description

What happens to a meal after it is eaten? Food consists primarily of lipids, proteins and carbohydrates (sugars). How do cells in the body process food once it is eaten and turned it into a form of energy that other cells can use? This book examines some of the classic experimental data that revealed how cells break down food to extract the energy. Metabolism of food is regulated so that energy extraction increases when needed and slows down when not needed. This type of self-regulation is all part of the complex web of enzymes that convert food into energy. Adding to this complexity is that all food eventually winds up as two carbon bits that are all processed the same way. This book will also reveal why animals breathe oxygen and how that relates to the end of the energy extraction process and oxygen’s only role in the body. Rather than look at all the details, this book takes a wider view and shows how cellular respiration is self-regulating.




Cellular Respiration and Carcinogenesis


Book Description

Cellular Respiration and Carcinogenesis presents leading experts in the field as it informs the reader about both basic and recent research in the field of cellular respiration and the effects of its dysfunction, alteration or attenuation on the development of cancer. This masterfully compiled text offers the reader a fundamental understanding about how oxygen sensing and/or availability, programmed cell death, immune recognition and response and glucose metabolism are intimately linked with the two major mechanism or pathways of cellular respiration; oxidative phosphorylation and glycolysis. The editors and contributing authors proficiently and unequivocally address the effects of dysfunction of the mitochondrial oxidative phosphorylation/glycolysis (cellular respiration) mechanisms and pathways on the development of cancer. While it remains true that there are no universal truths in cancer, Cellular Respiration and Carcinogenesis opens the dialogue that the etiology of cancer can usually be associated with, and significantly attributed to the failure of one or multiple pathways of oxidative phosphorylation (cellular respiration) to normally burn fuel to generate energy, vis-à-vis the Warburg hypothesis. Keeping with its cutting-edge nature, Cellular Respiration and Carcinogenesis provides the first glimpse to a cautionary evidence based counterbalance to the recent and rapidly proliferating notion that utilization of fuel primarily via glycolysis is a hallmark of cancer development.

Plant Respiration


Book Description

Respiration in plants, as in all living organisms, is essential to provide metabolic energy and carbon skeletons for growth and maintenance. As such, respiration is an essential component of a plant’s carbon budget. Depending on species and environmental conditions, it consumes 25-75% of all the carbohydrates produced in photosynthesis – even more at extremely slow growth rates. Respiration in plants can also proceed in a manner that produces neither metabolic energy nor carbon skeletons, but heat. This type of respiration involves the cyanide-resistant, alternative oxidase; it is unique to plants, and resides in the mitochondria. The activity of this alternative pathway can be measured based on a difference in fractionation of oxygen isotopes between the cytochrome and the alternative oxidase. Heat production is important in some flowers to attract pollinators; however, the alternative oxidase also plays a major role in leaves and roots of most plants. A common thread throughout this volume is to link respiration, including alternative oxidase activity, to plant functioning in different environments.




Principles of Biology


Book Description

The Principles of Biology sequence (BI 211, 212 and 213) introduces biology as a scientific discipline for students planning to major in biology and other science disciplines. Laboratories and classroom activities introduce techniques used to study biological processes and provide opportunities for students to develop their ability to conduct research.




Regulation of Tissue Oxygenation, Second Edition


Book Description

This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
