	The Realm of the Steady State in E. coli
		You thus see that there are two types of steady state - one in which the toaster sits equilibrated with room temperature and nothing is happening, and another in which current is flowing through and heating the toaster but the temperature has reached equilibrium and is unchanging.
		While the seed is almost in steady state (some very, very low levels of metabolism continue), the spore just sits there unchanged from minute to minute and day to day waiting for the right conditions to come along to induce germination.
		That is the realm of the dynamic steady state in a cell culture.

		Biochemistry is the study of the chemical processes and transformations in living organisms.
		Biochemistry studies the chemical properties of important biological molecules, like proteins, in particular the chemistry of enzyme-catalyzed reactions (enzymes are a type of protein).
		Although the term “biochemistry” seems to have been first used in 1882, it is generally accepted that the formal coinage of biochemistry occurred in 1903 by Carl Neuberg, a German chemist.

	Steady state (biochemistry) - Wikipedia, the free encyclopedia
		In ionic steady state, cells maintain different internal and external concentrations of various ionic species [1].
		The unequal distribution of ions represents a steady state (and not an equilibrium) as it requires the continual expenditure of cellular energy.
		Ionic steady state is a form of homeostasis.

	Steady state (disambiguation) - Wikipedia, the free encyclopedia

	Steady state (biochemistry) - Encyclopedia, History, Geography and Biography
		Cell membranes are permeable to sodium and various other ions, so in order to maintain a constant ionic concentration the cell must expend energy to actively transport these ions against the electrochemical gradient, out of the cell, at the same rate as they diffuse inward.
		The unequal distribution of ions represents a steady state (and not an equilibrium) as it requires the continual expenditure of cellular energy.

		Slow steady motion of a restraint device is calming, while sudden jerky motion excites.
		Observations of cattle in the kosher restraint box indicated that slow steady movements of the apparatus had a calming effect and sudden jerky motion excited the animals (Grandin 1994a, 1993a,c).
		These animals may be calm and quiet when they are in familiar surroundings such as their home ranch but they are more likely to panic when they are brought into the strange noisy environment of a meat packing plant or auction market.

	Steady state analysis of metabolic pathways using petri nets
		Structural analysis of metabolic systems in steady state aims at, among others, "elucidating relevant relationships among system variables" [Heinrich and Schuster, 1998] and does not rely on imperfectly known or doubtful kinetic data.
		A formalization of steady state and related notions is given in Schuster et al.
		In the long run, a steady state is approximated: according to the kinetic equations, those reactions with higher reactant (lower product) concentrations are preferred to those with lower reactant concentrations (or higher product concentrations, resp.).
