Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which contains energy. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical ...
The American Journal of Respiratory Cell and Molecular Biology is a monthly peer-reviewed medical journal and an official publication of the American Thoracic Society. It covers research on the structure and function of the respiratory system under physiologic and pathophysiologic conditions. It was established in July 1989.
Maintenance respiration in plants refers to the amount of cellular respiration, measured by the carbon dioxide (CO 2) released or oxygen (O 2) consumed, during the generation of usable energy (mainly ATP, NADPH, and NADH) and metabolic intermediates used for (i) resynthesis of compounds that undergo renewal (turnover) in the normal process of metabolism (examples are enzymatic proteins ...
At the University of Sheffield, Krebs and William Arthur Johnson investigated cellular respiration by which oxygen was consumed to produce energy from the breakdown of glucose. Krebs had earlier suggested to Warburg while they worked together in Germany that by using a manometer it could be possible to detect the oxygen consumption and identify ...
Maintenance respiration, the amount of cellular respiration required for an organism to maintain itself in a constant state; Respiration (physiology), transporting oxygen and carbon dioxide between cells and the external environment Respiratory system, the anatomical system of an organism used for respiration; Breathing, passing air in and out ...
Community respiration (CR) refers to the total amount of carbon-dioxide that is produced by individuals organisms in a given community, originating from the cellular respiration of organic material. CR is an important ecological index as it dictates the amount of production for the higher trophic levels and influence biogeochemical cycles . [ 1 ]
Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.
Chemiosmosis is the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient.An important example is the formation of adenosine triphosphate (ATP) by the movement of hydrogen ions (H +) across a membrane during cellular respiration or photosynthesis.
