Enzyme assay - Wikipedia
Enzyme activity = moles of substrate converted per unit time = rate × reaction volume. Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on conditions, which should be specified. The SI unit is the katal, 1 katal = 1 mol s −1, but this is an excessively large unit.
Factors affecting Enzyme Activity | A Level Notes
Factors affecting Enzyme Activity. The activity of an Enzyme is affected by its environmental conditionshanging these alter the rate of reaction caused by the enzyme. In nature, organisms adjust the conditions of their enzymes to produce an Optimum rate of reaction, where necessary, or they may have enzymes which are adapted to function well in extreme conditions where they live.
