You are investigating the structure of the seeds of a newly discovered tropical plant. There is storage material inside the seed. You treat the seed with peptidase (an enzyme that breaks peptide bonds),
glycoside hydrolases (an enzyme that breaks ? glycosidic bonds), and amylase (an enzyme that breaks ? glycosidic bonds). Only the amylase appears to dissolve the storage material in the seed. What does this tell you about the identity of the storage material?
A) The seed contains fibrous proteins to store carbon and energy.
B) The seed contains lipids to store carbon and energy.
C) The seed contains starch to store carbon and energy.
D) The seed contains cellulose to store carbon and energy.
E) The seed contains globular proteins to store carbon and energy.
