Question

which of the following are true about cellulose? (2) *
it is a major component of plant cell walls
it is soluble
it is a polmer of two types of monomer α - glucose & β - glucose
it is the most abundant carbohydrate
what atoms make up all carbohydrates? *
carbon, sulfur, hydrogen
carbon, oxygen, phosphorus
carbon, oxygen, nitrogen
carbon, oxygen, hydrogen

Explanation:

• Cellulose:
• Cellulose is indeed a major component of plant cell walls. It provides structural support to plant cells.
• Cellulose is insoluble in water. Its long, linear chains of glucose units (linked by β - 1,4 - glycosidic bonds) form a rigid, fibrous structure that does not dissolve easily.
• Cellulose is a polymer of β - glucose only. Starch, for example, is a polymer of α - glucose.
• Cellulose is the most abundant carbohydrate on Earth. It is found in large quantities in plant cell walls.
• Carbohydrates:
• The general formula for carbohydrates is \(C_x(H_2O)_y\). This shows that they are made up of carbon (\(C\)), hydrogen (\(H\)), and oxygen (\(O\)) atoms. Sulfur (\(S\)), phosphorus (\(P\)), and nitrogen (\(N\)) are not part of the basic structure of all carbohydrates.

Answer:

• For the cellulose question:
• It is a major component of plant cell walls.
• It is the most abundant carbohydrate.
• For the atoms in carbohydrates question: Carbon, Oxygen, Hydrogen.
