  1. membrane
    • phospholipid bilayer
    • fxn: control in/out materials for cell
  2. mitochondria
    • fxn: make cellular energy
    • in the form of ATP
    • using O2
    • in the Kreb's Cycle
  3. rER
    • rough endoplasmic reticulum
    • fxn: makes proteins
    • for secretion
    • or membrane
  4. sER
    • smooth endoplasmic reticulum
    • fxn: makes lipids
    • fats
    • steroids
  5. free ribosomes
    fxn: make protein for cell's own use
  6. Golgi body
    • fxn: process and package proteins
    • and some lipids
    • for secretion
  7. Secretory vesicle
    fxn: exocytosis
  8. lysosome
    • vesicle contains enzyme
    • fxn: digest/breakdown
    • old/broken
    • proteins
    • organelles
    • bacteria
  9. peroxisome
    • vesicle contains enzymes
    • fxn: detoxify
    • unwanted chemicals
  10. Nucleus
    • fxn: hold DNA
    • make RNA
  11. Desmosomes
    • protein point connection between cells
    • fxn: filtration barrier
    • ex/: small ions/molecules
    • can go between cells
    • but large ones cannot
  12. Tight Junction
    • band of protein around cells to hold them together 
    • fxn: prevent anything from going between cells 
    • ex/: transitional epithelium
    • bladder
    • urinary tract
  13. Gap Junctions
    • protein channel between cells 
    • fxn: ions move from cell to cell 
    • ex/: heart
    • digestive
    • skeletal
    • A- Nuclear membrane
    • B- Mitochondria 
    • C- Smooth ER
    • D- Rough ER
    • G- Nucleus
