Describe the arrangement of glucose molecules in cellulose.

• Linear polymer of glucose molecules linked by beta-1,4-glycosidic bonds

• No specific arrangement of glucose molecules

• Spherical arrangement of glucose molecules

• Random arrangement of glucose molecules

What type of bond holds the glucose molecules together in cellulose?

• Beta-1,4-glycosidic bonds

• Ionic bonds

• Hydrogen bonds

• Covalent bonds

How does the chemical structure of cellulose differ from starch?

• Cellulose has beta 1-4 linkages, while starch has alpha 1-4 linkages.

• Cellulose has alpha 1-4 linkages, while starch has beta 1-4 linkages.

• Cellulose and starch have the same chemical structure.

• Cellulose is made up of glucose molecules, while starch is made up of fructose molecules.

Explain the significance of cellulose in plant cell walls.

• Cellulose provides structural support and rigidity to plant cell walls.

• Cellulose is responsible for the color of plant cell walls.

• Cellulose is used by plants for energy storage.

• Cellulose helps in the process of photosynthesis in plant cells.

How many hydrogen bonds can a single glucose molecule in cellulose form?

• Multiple

• Two

• One

• None

What role do hydrogen bonds play in the strength of cellulose fibers?

• Hydrogen bonds weaken the cellulose fibers

• Hydrogen bonds form strong intermolecular interactions between cellulose chains.

• Hydrogen bonds have no effect on the strength of cellulose fibers

• Hydrogen bonds cause cellulose fibers to break down

Compare the strength of hydrogen bonds in cellulose with other types of bonds.

• Weaker than other types of bonds

• No difference in strength compared to other types of bonds

• Not involved in bonding with other molecules

• Stronger than other types of bonds

Explain how hydrogen bonding contributes to the insolubility of cellulose in water.

• Hydrogen bonding between cellulose molecules makes it difficult for water molecules to break the strong intermolecular forces and interact with the cellulose molecules.

• Hydrogen bonding between cellulose and water makes it easier for water to break the intermolecular forces.

• Cellulose is soluble in water due to the strong hydrogen bonding between cellulose and water.

• Cellulose is insoluble in water because it lacks hydrogen bonding.

Discuss the impact of hydrogen bonding on the biodegradability of cellulose.

• Hydrogen bonding in cellulose has no impact on its biodegradability

• Hydrogen bonding in cellulose makes it more resistant to biodegradation.

• Hydrogen bonding in cellulose has a neutral effect on its biodegradability

• Hydrogen bonding in cellulose accelerates its biodegradation
