2.1.2 (f) Glycogen and starch

Which is the correct order for these polysaccharides, starting with the most branches to least.

• Glycogen, amylose, amylopectin

• Glycogen, amylopectin, amylose

• Amylose, glycogen, amylopectin

• Amylose, amylopectin, glycogen

Which monosaccharide makes up amylose and amylopectin?

• Alpha glucose

• Beta glucose

• Maltose

• Starch

Which carbon number is the arrow pointing to in the image?

• 1

• 2

• 3

• 4

A molecule of amylopectin is made up of:

• alpha-glucose molecules joined by 1-4 and 1-6 glycosidic bonds

• beta-glucose molecules joined by 1-4 and 1-6 glycosidic bonds

• alpha-glucose molecules joined by 1-4 glycosidic bonds only

• beta-glucose molecules joined by 1-4 glycosidic bonds only

What is the function(s) of amylose, amylopectin, glycogen?

• Structure of cell wall.

• Structure of cell membrane.

• Energy storage molecule.

• Maintain water potential of the cytosol.

Glycogen (in animals) is more branched than amylopectin (in plants). Why is this important?

• More compact.

• Less compact.

• More free ends for glucose to be added / removed.

• Animals produce more glucose than plants.
