WebEnzyme Activity(μmol/min ml) or (U/ml) = (Consumed Substrate) ×Total Reaction Volume / (Reaction time (min)) × (Enzyme volume(ml)) WebTo catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. shire massage therapy gary morrisonWebEnzymes are reusable. Enzymes are not reactants and are not used up during the reaction. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules. shire masland carpet
