steady-state velocity

(redirected from steady-state rate)

stead·y-state ve·loc·i·ty

the velocity of an enzyme-catalyzed reaction in which, over the time course of the study, the concentration of any enzyme species is constant (that is, for an enzyme-substrate binary complex, ES, d[ES]/dt ≈ 0; for this to hold true, the total enzyme concentration must be much less than the initial substrate concentration.

Firstly, as described previously, there is a steady-state rate of HIV-infected patients who should be entering the ART programme each year.
The topics include basic principles of chemical kinetics, deriving steady-state rate equations, reactions of more than one substrate, the effect of pH on enzyme activity, multi-enzyme systems, and estimating kinetic constants.
18) Finally, what one would ultimately like to know is the effect of a change in [mu] on the steady-state rate of return on real balances or, in other words, on the inverse inflation rate [p.
From a vehicle at pH 2, the steady-state rate of penetration was very low and the data suggested drug binding by stratum corneum.
In a case 2 economy, a higher rate of money creation (a higher steady-state rate of inflation) reduces the per capita capital stock and per capita output.
This formulation implies that the unemployment rate would decline in response to an increase in the inflation rate but would be invariant to any steady-state rate of inflation.
The money supply grows one-for-one with output, and given an income elasticity of one and an interest elasticity of zero, its behavior is consistent with prices growing at their steady-state rate of 2 percent.
If growth is above the steady-state rate (and hence u [is less than] u*) increased demand for saving cuts demand for output and, by reducing capacity utilisation, reduces the incentive for capital accumulation.
The volumetric feed system used to provide the magnesium alloy to the Thixomolder is initially set at 25% of the steady-state rate, then ramped up to 100% as the machine progresses from making partial shots to complete shots.
DIMAC is a polymer matrix system which can store many types and classes of drugs and chemical agents and releases the embodied material in a desirable steady-state rate so that the optimal clinical response is achieved.
To do the Ames test, these chemical mixes had to be held in a constant steady-state rate of reaction for 18 hours, something not possible in the ambient atmosphere.
75% steady-state rate for the life of the bonds, which also appears optimistic given historical rates of growth that have been in double-digits in recent years.
