While performing an experiment on the enzyme amylase, macy uses three different ph solutions: ph 3.0, ph 4.0, and ph 6.7. she finds that all the starch is broken down fastest at ph 6.7. how would you justify these findings? the optimum ph for amylase is ph 6.7, at which the rate of reaction is the highest. the minimum ph for amylase is ph 6.7, after which the reaction takes minimum time for completion. the optimum ph of amylase is between ph 3.0 and ph 4.0, at which the enzyme takes maximum time for completion. nextreset
