Web11 de out. de 2003 · We will need to keep the volume of reactants the same as if we use different volumes it will create anomalous results. For example, we are using a 1:10 ratio of enzyme:substrate (2mm neutrase, 20mm Marvel milk). If we were to change the ratio to 4:10 then the enzyme would work faster and we would be getting inaccurate results. Web3. Hydrolysis.
