-The enzyme amylase can break glycosidic linkages between glucose monomers only if the monomers are the α form. Which of the following could amylase break down?
A)glycogen, starch, and amylopectin 
B)glycogen and cellulose 
C)cellulose and chitin 
D)starch and chitin 
E)starch, amylopectin, and cellulose

Quizplus · Accepted Answer

Glycogen, starch, and amylopectin are composed of glucose monomers linked together by α glycosidic linkages, which can be broken by amylase. Cellulose and chitin, on the other hand, have β glycosidic linkages between their glucose monomers, which cannot be broken by amylase.
