The subunits (monomers) in cellulose are linked together by __________.

• A. ionic bonds
• B. peptide bonds
• C. phosphodiester linkages
• D. ester linkages
• E. glycosidic linkages

Answer: (E)

Verified step by step guidance

1. Begin by identifying the structure of cellulose. Cellulose is a polysaccharide, which means it is composed of sugar molecules linked together.
2. Understand the type of monomers that make up cellulose. Cellulose is made up of glucose monomers.
3. Recognize the type of bond that typically links sugar molecules in polysaccharides. These are known as glycosidic linkages.
4. Differentiate glycosidic linkages from other types of bonds listed in the options: ionic bonds, peptide bonds, phosphodiester linkages, and ester linkages. Glycosidic linkages are specific to carbohydrates.
5. Conclude that the monomers in cellulose are linked by glycosidic linkages, which are covalent bonds formed between carbohydrate molecules.
