What is the purpose of using a dropping pipette in the enzyme activity investigation?

The purpose of using a dropping pipette in an enzyme activity investigation is primarily to deposit the amylase solution with precision. By using a pipette, researchers can control the volume and the rate at which the enzyme solution is added to the substrate (like starch). This careful addition is crucial for accurately measuring the enzyme's activity, as even slight variations in the amount of enzyme can significantly affect the reaction rate.

Using a dropping pipette allows for easy handling and minimizes the risk of contamination or exposure to the enzyme outside the controlled setting of the assay. This controlled method aids in ensuring that the investigation yields reliable results regarding how the enzyme functions under the specific conditions being studied.
