How to measure enzyme reaction rate

WebThe rate of enzyme-catalyzed reactions can be measured by monitoring the appearance or disappearance of the substrate or product over time. →How do enzymes speed … The quantity or concentration of an enzyme can be expressed in molar amounts, as with any other chemical, or in terms of activity in enzyme units. Enzyme activity is a measure of the quantity of active enzyme present and is thus dependent on various physical conditions, which should be specified. It is calculated using the following formula:
