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 polymer 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 a major structural component of plant cell walls.
• It is insoluble in water.
• It is a polymer of β - glucose (not a mixture of α - glucose and β - glucose).
• It is the most abundant carbohydrate on Earth.
• Carbohydrates:
• The general formula of carbohydrates is \(C_x(H_2O)_y\). So, they are made up of carbon (C), hydrogen (H), and oxygen (O) atoms.

Answer:

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