Question

look at the molecule shown below. what can you tell me about this molecule? this molecule is a monosaccharide. this molecule is not a sugar. the molecule is an amino acid. the molecule is a disaccharide. the molecule is a polysaccharide. 2.5 pts question 2 how could a polysaccharide be broken down into individual monosaccharides? an enzyme can form a glycosidic linkage via a dehydration synthesis reaction. an enzyme can break a glycosidic linkage via a hydrolysis reaction. enzymes are not involved in breaking down polysaccharides. an enzyme can break a glycosidic linkage via a dehydration synthesis reaction.

Explanation:

1. The molecule shown has two sugar - ring structures joined by a glycosidic bond, which is characteristic of a disaccharide. Monosaccharides are single sugar units, polysaccharides are long chains of sugar units, and it is not an amino acid (which has an amino and a carboxyl group).
2. Polysaccharides are broken down into monosaccharides by enzymes breaking the glycosidic linkages through hydrolysis reactions. Dehydration synthesis is for building up polymers, not breaking them down.

Answer:

1. The molecule is a disaccharide.
2. An enzyme can break a glycosidic linkage via a hydrolysis reaction.
