Question 11: How do cellulose and starch differ?

• cellulose and starch are proteins with different R groups
• cellulose and starch are both polysaccharides made up of glucose molecules, but they are

connected with different types of bonds

• cellulose is a polysaccharide made up of glucose molecules and starch is a polysaccharide

made up of galactose molecules

• cellulose and starch are the same molecule, but cellulose is made by plants and starch is

made by animals

Answer:

• cellulose and starch are both polysaccharides made up of glucose molecules, but they are connected

with different types of bonds -both polysaccharides of glucose which gives them different structures and functions
