Define specific activity of enzyme
WebEnzymes can be regulated by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are called activators, while molecules that decrease the activity of an enzyme are called inhibitors. WebEnzyme Activity (μmol/min ml) or (U/ml) = (Concentration of product of reaction) (μmol /ml) ×Total Reaction Volume (ml) / [ (Reaction time (min)) × (Enzyme volume (ml))] Cite 13...
