Which of the following is not a substrate for amylase?

Explanation:
Amylase targets α-1,4 glycosidic bonds in glucose polymers, so it readily hydrolyzes starch and related polymers like amylose and glycogen, which contain those α linkages. Cellulose is built from β-1,4 linkages between glucose units, and amylase cannot cleave these bonds, plus humans don’t produce cellulase to digest cellulose. That mismatch in bond type is why cellulose is not a substrate for amylase.
