Q

What are the main properties of storage polysaccharides?

A
  • Compact (Helical and branched)
  • Inert so it can’t diffuse out of the cell
  • Insoluble in water so it doesn’t lower the cells water potential
  • Branched so there are several ends for enzyme attachment.
  • Quickly broken down into glucose

  • Found in chloroplasts or amyloplasts in plant cells depending on the need of the plant cell
  • Stored at granules

Q

How is the structure of cellulose linked to its function?

A
  • Hydrogen bonds between adjacent molecules form microfibrils which bundle together to form fibres.
  • Fibres provide high tensile strength
  • Prevents cell wall from bursting under osmotic pressure
  • Fibre provides flexibility and reinforcement to the cell wall which gives the cell high tensile strength and allows it to be under turgor pressure.
17
Q

What are polymers?

A

Large, complex molecules composed of long chains of monomers joined together.

18
Q

What are monomers?

A

Small, basic molecular units.
