alleryStart learning →Glucose monomers are the building units of which three polymers?
AStarch, glycogen and cellulose
BStarch, glycogen and chitin
CStarch, cellulose and chitin
DGlycogen, cellulose and chitin
Answer & Solution
Correct answer: A. Starch, glycogen and cellulose
1. One kind of monomer can be joined in several configurations, giving different polymers.
2. Glucose is the worked example: it builds starch, glycogen and cellulose.
3. Chitin is a different case, because its repeating unit is a modified sugar that carries nitrogen.
4. So any list that includes chitin among the glucose polymers is wrong.
