3. Endoplasmic Reticulum: Structure
Network of membranous channels
Rough ER - studded with ribosomes
Smooth ER - no ribosomes

4. Ribosomes

5. Processes and sorts proteins to be secreted out of cell
Rough ER: Function
Processes and sorts proteins to be secreted out of cell
Sends proteins in vesicles that pinch off from the membrane

6. Smooth ER: Structure
No ribosomes attached

7. Golgi Apparatus

8. Makes lipids and carbos Detoxifies poisons
Smooth ER: Function
Makes lipids and carbos
Detoxifies poisons
Stores and releases Ca+2 ions
Removes phosphate group from glucose so can leave cell

9. Golgi Apparatus (Bodies): Structure
Flattened stack of membranes (not continuous)

10. Golgi Apparatus: Function
Modifies, sorts, packages, and transports proteins from ER
Forms transport vesicles

12. Digest damaged or worn out organelles
Lysosomes: Function
Digest damaged or worn out organelles
Digest entire cells
