Question

which pair of statements best compares the primary functions of the carbohydrate chitin and the protein chitinase?
(a) the chitin in the exoskeleton provides insulation for insects. the chitinase stores genetic material for insectivorous bats.
(b) the chitin in the exoskeleton breaks down for energy to be used by insects. the chitinase provides insulation for insectivorous bats.
(c) the chitin in the exoskeleton stores genetic material for insects. the chitinase provides insulation for insectivorous bats.
(d) the chitin in the exoskeleton provides support and protection for insects. the chitinase breaks down chitin for energy to be used by insectivorous bats.

Explanation:

Chitin is a polysaccharide that forms the exoskeleton of insects, providing support and protection. Chitinase is an enzyme that breaks - down chitin. Insectivorous bats can use the energy released from the breakdown of chitin by chitinase.

Answer:

D. The chitin in the exoskeleton provides support and protection for insects. The chitinase breaks down chitin for energy to be used by insectivorous bats.
