  • Organelles
    • Nucleus
      • Has nuclear pores so it allows large molecules out of the nucelus
      • Controls cell activity using coded instructions
      • Has a nucleolus to manufacture RNA
    • Endoplasmic reticulum
      • Rough endoplasmic reticulum
        • Synthesizes proteins and glycoproteins
          • So it has a large surface area
        • Has ribosomes to assemble proteins
          • Ribosomes have a small surface area so they can have a large overall surface area
      • Smooth endoplasmic reticulum
        • Reactions involving lipids (e.g. breaks down lipid based chemicals)
    • Golgi body
      • Processes proteins e.g add carbohydrate, label for destination and put in vesicles
    • Mitochondrion
      • Releases energy from glucose to make ATP
      • Has folded cristae so it has a large surface area for lots of reactions
      • It is narrow so it has a short diffusion distance
  • Smooth endoplasmic reticulum
    • Reactions involving lipids (e.g. breaks down lipid based chemicals)
