1.1. State two properties of starch that make it an effective storage polysaccharide. 

1.2. Amylopectin has a highly branched structure caused by the different types of glycosidic bonds between the monomers. 

Fig. 1 shows a diagram of a section of amylopectin with two different types of glycosidic bonds labelled. 

Fig.1

(i) Complete the labels on Fig. 1 to name the types of glycosidic bonds in amylopectin.

(ii) For the two bonds you've labelled in part (i), explain the science behind the different names.

1.3. Glycogen has an even more branched structure than amylopectin, which makes it ideal as an energy storage molecule in animal cells.

Describe how the branched structure of glycogen helps fulfill its role as a short-term energy storage compound. 

1.4. Fig. 2 shows a cell from a garden pea.

Fig. 2

Describe how you could determine if the granules contained starch.
