Complete hydrolysis of a certain macromolecule isolated from plant tissue yields only fructose molecules. Identify the macromolecule and the specific type of bond that is broken during this process.

Step-by-step solution

The macromolecule that yields only fructose upon complete hydrolysis is inulin, which is a homopolymer of fructose found in plants. Because inulin is a polysaccharide, its monosaccharide monomers (fructose) are linked together by glycosidic bonds. Hydrolysis of inulin involves the breaking of these glycosidic bonds. Insulin is a protein hormone (linked by peptide bonds) and yields amino acids. Cellulose yields glucose. Phosphodiester bonds are found in nucleic acids. Answer: Inulin and glycosidic bond
