  respiration - Hutchinson encyclopedia article about respiration
Aerobic respiration is a complex process of chemical reactions in which oxygen is used to break down glucose into carbon dioxide and water.
Respiration at the cellular level is termed internal respiration, and in all higher organisms occurs in the mitochondria.
Respiration – the release of energy within cells – is a complex series of reactions which employs about 70 different enzymes that act as catalysts.

 Respiration (physiology) - Wikipedia, the free encyclopedia
Respiration is the process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy).
Respiration takes place on a cellular level whereas breathing is on a different level.
Respiration takes place in the mitochondria of the cells and provide the cells with energy.

 AllRefer.com - respiration (Anatomy And Physiology) - Encyclopedia
The term now refers to the overall process by which oxygen is abstracted from air and is transported to the cells for the oxidation of organic molecules while carbon dioxide (CO) and water, the products of oxidation, are returned to the environment.
Organisms that utilize respiration to obtain energy are aerobic, or oxygen-dependent.
Some organisms can live in the absence of oxygen and obtain energy from fuel molecules solely by fermentation or glycolysis; these anaerobic processes are much less efficient, since the fuel molecules are merely converted to end products such as lactic acid and ethanol, with relatively little energy-rich ATP produced during these conversions.

 Plant Physiology: Photosynthesis, Respiration and Transpiration   (Site not responding. Last check: 2007-10-13)
O, Respiration — the process of metabolizing (burning) sugars to yield energy for growth, reproduction and other life processes, and Transpiration — the loss of water vapor through the stomata of leaves.
Notice that the equation for respiration is the opposite of photosynthesis.
Again, respiration is the burning of sugars for energy to grow and do the internal work of living.

 Plant Physiology Online: Role of Respiration in Desiccation Tolerance
Respiration exerts a dual effect on the survival of plant cells undergoing water loss.
Sufficient respiration is necessary to generate the chemical energy required for the production of molecules that protect against the adverse effects of water loss.
If initially, rapidly respiring systems nevertheless tolerate desiccation to the air-dry state with the help of a superior antioxidant defense, then they tend to be more short-lived than less metabolically active systems.

He was born in Timisoara in 1806 and he finished the first Book of Physiology in 1830, which uses for the first time Romanian anatomical and physiological terminology and was to appear in Buda, under the title: "Anthropology" or "Brief Approacha to Man and his Features".
The history of Physiology begins in the university year 1945-1946, at the time when the head of the Department was Professor Ilie Georgescu (1905-1963), M.D., Ph.D., "Docteur de L`Université de Paris", "Magna cum laudae".

In contrast, respiration is widely accepted to double with each 10 ÂșC increase in temperature, but this relationship is derived from short-term (hours) measurements in mature organisms.
Respiration is widely accepted to double with each 10C increase in temperature (a 100% increase), but this relationship is derived from short-term (hours) measurements in mature organisms.
While both components may play a role in determining respiration rates, their relative contributions are poorly characterized, and we do not understand the short-term respiratory adaption of plant communities to environmental changes such as warm sunny days followed by cool cloudy days.

For example, dry air is composed of approximately 21% oxygen (actually 20.9%), and 79% nitrogen (actually, nitrogen is closer to 78%, with the remaining 1% consisting mainly of argon; for purposes of respiration, we usually lump the inert gases with nitrogen).
The one gas to which this applies in a normal respiration is water.
The lungs and airways are always moist, and inspired gas is rapidly saturated with water vapor in the upper segments of the respiratory system.

 Lawn Care
Storage products are utilized for respiration during periods of stress to help maintain the plant when photosynthesis is not occurring or occurring at a low level.
In spring (condition 2) photosynthesis increases because it is cool and sunny, respiration is minimal because of cool temperatures, and growth is naturally increasing which slightly depletes storage.
During the heat of summer (condition 4) photosynthesis is down because of the temperature, respiration is up also because of the temperature, growth is reduced, and storage decreases because it is being used to supply respiration.
