Q

Why does cellulose make a good structural molcule

A

Cellulose has hydrogen bonds between chains and forms layers of fibres that give it tensile strength. It is also permeable and allows necessary molecules into the cell

17
Q

How does glycogen differ from starch

A

Glycogen has shorter glycosidic links so it is much more branched and is only found in animals

18
Q

A

two glucose units

19
