Question: how long does it take for amylase to digest starch?
Answer: a Check the speed of the reaction with the suggested volumes of reactants to be used – 2 cm3 of starch: 2 cm3 of amylase: 1 cm3 of buffer at pH 6. Ideally the reaction should take about 60 seconds at this pH: this is the usual optimum for amylase (see note 1).
