What is the general formula for amylopectin?

(C5H10O5)n

(C5H10O6)n

(C6H12O6)n

(C6H10O5)n

Which statement describes how the molecular structure of starch is suited to its function?

Amylose has a branched structure and amylopectin is coiled to give a compact molecule for transport

In the breakdown of amylose and amylopectin, many condensation reactions release stored energy 

In the formation of amylose and amylopectin, many hydrolysis reactions allow the release of stored energy

The amylose-amylopectin complex is insoluble and does not affect the water potential of the cell

Which monomer is found in each of cellulose, glycogen, amylopectin and amylose?

x = cellulose  y=glycogen  x= amylopectin  y=amylose

x = cellulose  y=glycogen  y= amylopectin  y=amylose

y = cellulose  x=glycogen  x= amylopectin  x=amylose

y = cellulose  x=glycogen  y= amylopectin  x=amylose

Chitin is a polysaccharide consisting of long straight chains of the monosaccharide acetylglucosamine, linked by 1,4 glycosidic bonds.
Acetylglucosamine is similiar in structure to glucose, but contains nitrogen, allowing hydrogen bonds to form between adjacent chains of chitin when they lie parallel to one another.

Which polysaccharide is most similiar in structure to chitin?

Amylopectin

Amylose

Cellulose

Glycogen
