Being a secreted enzyme, that amylase is pretty durable so it might 
persist for some time in an active state after it has done its job. 
Amylase is fairly easy to assay so perhaps you could convince the 
student to do an experiment to see how long it remains in the drying 
tissue after the endosperm is spent!

Hmmm, I wonder how much denatured amylase remains in beer?
