[Effect of rapid changes of the oxygenation state and other external parameters on the long-term behavior of the energy metabolism in the erythrocyte].
The red blood cell when transported through the circulatory system is exposed to a steady (approximately periodical) change of environmental conditions causing a permanent fluctuation of its important metabolic parameters. In a simple theoretical model it is demonstrated that a rapid oscillation of such parameters may stabilize a metabolic state which will collapse when this oscillation breaks off. The hypothesis is advanced that parameter oscillations caused by the physiological function of the red blood cell may be of importance for the maintenance of its energy metabolism and that the break-off of these oscillations may be a potential cause for the metabolic collapse, e.g. in stored blood.
