Explanation:
The paper presents a generic computer model for estimating short-term steady-state fluxes of CO2, water vapor, and heat from broad leaves and needle-leaved coniferous shoots of C3 plant species. The model explicitly couples all major processes and feedbacks known to impact leaf biochemistry and biophysics including biochemical reactions, stomatal function, and leaf-boundary layer heat- and mass-transport mechanisms. The ability of the model to successfully predict measured photosynthesis and stomatal-conductance data as well as to simulate a variety of observed leaf responses is demonstrated. A model application investigating physiological and environmental regulation of leaf water-use efficiency (WUE) under steady-state conditions is discussed. Simulation results suggest that leaf physiology has a significant control over the environmental sensitivity of leaf WUE. The implementation of a highly efficient solution technique allows the model to be directly incorporated into plant-canopy and terrestrial ecosystem models.
Answer:
The study of biophysical and biochemical mechanisms of maintenance stability Internal Energy and Internal Medium an organism must help provide medical activity as for health care of able-bodied organisms as well as for choice of treatment some diseases. Just stability Internal Energy and Internal Medium of an organism is maintained by three levels of Regulations: Highest level regulation – Central Nervous System; High level regulation - Equilibrium Constants of ionic metabolism, Equilibrium Constants of acid – alkaline metabolism, Equilibrium Constants of oxidative – reductive Potentials of metabolism, Equilibrium Constants of coagulating system of a blood; Low level regulation - Equilibrium Constants of anabolic endergonic biosynthetic processes and catabolic exergonic oxidative processes, Equilibrium Constants of anabolic and catabolic processes. The biophysical and biochemical mechanisms of maintenance stability Internal Energy and Internal Medium an organism operate via the system of regulation of interaction between biochemical and biophysical processes an organism with Environment. Therefore study regulative mechanism an organism is the basis of study the biophysical and biochemical mechanisms of maintenance stability Internal Energy and Internal Medium an organism. Considering interactions between a human organism and environment in normal stationary state and transition into pathologic quasi-stationary states, it was exhibited and elucidated the mechanism regulation of maintenance stability Internal Energy and Internal Medium as of an organism as well as of cells an organism both in norm and in pathology from the point of view of thermodynamics, biophysics and biochemistry. Thus regulative mechanism of an organism was divided into three levels: highest level regulation, high level regulation and low level regulation. Influences of Environment on an organism occur through low level of regulation, and an organism’s defensive reactions against these influences of Environment are realized by mechanism regulation of maintenance stability Internal Energy and Internal Medium of as an organism as well as cells of an organism which structure and mechanism operation were elucidated in the article. Moreover the mechanisms regulation of maintenance stability Internal Energy and Internal Medium are changed corresponding to the positive fluctuations of entropy during the life both an organism and cells of an organism that was also reflected, and mechanisms of these changes were elucidated. Also the mechanisms of violations mechanisms regulation of maintenance stability Internal Energy and Internal Medium of as an organism as well as cells of an organism in some pathological processes are explained from the point of view of thermodynamics, biophysics and biochemistry. Critical reviews of some investigations of the pathological processes, studying the defensive immune mechanisms and the other mechanisms of restoration stability Internal Energy and Internal Medium of an organism, were represented and explained as the mechanisms regulation of these processes as well as possible modes of some pathologic processes treatment.
