Q

Glycogen:

  • hydrolysis?
  • shape?
  • type of glycosidic bond?
  • osmotic affect?
A
  • rapid hydrolysis because it’s branched
  • spherical
  • alpha glucose 1-4 and 1-6
  • no effect

Q

Amylose:

  • hydrolysis?
  • shape?
  • type of glycosidic bond?
  • osmotic affect?
A
  • Slow hydrolysis for respiration because there are only 2 enzyme attachment points (doesn’t matter anyway because plants respire slowly)
  • coiled
  • alpha glucose 1-4
  • fewer OH groups (bc compact) exposed on helix so less of an osmotic affect
