starch, glycogen and cellulose Flashcards
what is starch
polysaccharide
what bonds and reaction of starch
glycosidic and a condensation reaction
what is the main role of starch
its an energy store
what is the structure of starch
It’s insoluble so it does not affect water potential
It’s large so it does not diffuse out of cells
its compact os it can be stored in small places
what is the structure of glycogen
It’s insoluble so it does not draw water in the cell
it is insoluble so it does not diffuse out the cell
It’s compact so it can be stored in small places
what does cellulose do for the cell wall
it provides turgidity
what is the structure of cellulose
cellulose molecules are made up of beta glucose
cellulose molecular chain run parallel and are crossed linked by hydrogen bonds
these molecules are grouped to form microfibrials
