Multiple Choice

Refer to the figures below. A student claims that adding functional groups onto carbohydrates does not provide any biological advantage.Which statement best evaluates this claim, using cellulose and chitin as evidence for the student's argument?

• A) The student's claim is valid, as shown by cellulose and chitin, which both serve the same biological role even though one has a chemical modification and the other does not.
• B) The student's claim is valid, as shown by cellulose and chitin, which require different enzymes for their synthesis and breakdown and thus create additional demands on cells.
• C) The student's claim is not valid, as shown by cellulose and chitin, which allow the same organism to have greater flexibility in the type of structural polysaccharide it can build.
• D) The student's claim is not valid, as shown by cellulose and chitin, which have different properties that enable different structures to develop in different organisms.
• E) The student's claim is not valid, as shown by cellulose and chitin, which have vastly different biological functions as the result of chemical modification in one and not the other.
