The movement of something into, through and out of a place, the rate at which a thing is depleted and replaced. 
turnover. The movement of something into, through and out of a place, the rate at which a thing is depleted and replaced. Please contribute to this project, if you have more information about this term feel free to edit this page. Turnover Number (Molecular Biology). T he turnover number for an enzyme-catalyzed reaction is defined as the number of moles of substrate converted to product per mole of enzyme per second under conditions at which the concentration of all substrates is saturating. Turnover numbers are expressed in units of s-1. turnover number. (Science: biochemistry, pharmacology) equivalent to vmax, being the number of substrate molecules converted to product by one molecule of enzyme in unit time, when the substrate is saturating.

T he turnover number for an enzyme-catalyzed reaction is defined as the number of moles of substrate converted to product per mole of enzyme per second under conditions at which the concentration of all substrates is saturating. Turnover numbers are expressed in units of s-1. Turnover. Turnover. Metabolism is a dynamic process. The cell is continuously degrading and synthesizing molecule s. In general, the catabolic pathways are providing energy in the form of ATP that is used to drive the anabolic processes. Explain turnover rate and optimum conditions as related to enzymes.
