Flux is the net movement of particles across a specified area in a specified period of time. [1] The particles may be ions or molecules, or they may be larger, like insects, muskrats or cars. The units of time can be anything from milliseconds to millennia. Flux is not the same as velocity or speed nor is it the same as density or concentration.
Flux is therefore of great interest in metabolic network modelling, where it is analysed via flux balance analysis and metabolic control analysis. In this manner, flux is the movement of matter through metabolic networks that are connected by metabolites and cofactors , and is therefore a way of describing the activity of the metabolic network ...
Flux (biology), movement of a substance between compartments; Flux (metabolism), the rate of turnover of molecules through a metabolic pathway; 4-Fluoroamphetamine (4-FA; PAL-303; "Flux"), a central nervous system stimulant with quasi-amphetamine effects; Dysentery, or other diseases called "flux", which cause the loss of fluid by diarrhea or ...
Fluxomics describes the various approaches that seek to determine the rates of metabolic reactions within a biological entity. [1] While metabolomics can provide instantaneous information on the metabolites in a biological sample, metabolism is a dynamic process. [2]
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
In the latter case flux can readily be integrated over a surface. By contrast, according to the electromagnetism definition, flux is the integral over a surface; it makes no sense to integrate a second-definition flux for one would be integrating over a surface twice. Thus, Maxwell's quote only makes sense if "flux" is being used according to ...

[9] [10] [11] [7] Biology is the main driver of O 2 flux on modern Earth, and the evolution of oxygenic photosynthesis by bacteria, which is discussed as part of the Great Oxygenation Event, is thought to be directly responsible for the conditions permitting the development and existence of all complex eukaryotic metabolism.
