Question

The enzyme amylase can break glycosidic linkages between glucose monomers only if the monomers are in the alpha form. Which of the following could amylase break down?
a. glycogen, starch, and amylopectin
b. glycogen and cellulose
c. cellulose and chitin
d. starch, chitin, and cellulose

Answer 1

Answer:

The correct option is: a. glycogen, starch, and amylopectin

Explanation:

Glycogen, amylopectin and starch are the polysaccharides of glucose. These polymers are composed of monomeric α-glucose units, which are joined by α(1→4) glycosidic bonds.

Since, the amylase enzyme can act only on the glycosidic bonds formed between α-glucose monomers. Therefore, amylase can break down glycogen, starch, and amylopectin.
