Endomembrane System

Membranes within the eukaryotic cell that

work together to modify, process and ship

molecules around and out of the cell.

Endomembrane System

  • All made of phospholipid bilayer
  • Includes:
    • Nuclear envelope
    • Rough ER
    • Smooth ER
    • Transport vesicles
    • Golgi apparatus
    • Lysosomes
    • Secretory vesicles

What about Ribosomes?

ATTACHED TO ER

Makes proteins that are stored in vesicles or released from the cell.

FREE FLOATING IN CYTOPLASM

Makes proteins that are used immediately in the cytoplasm.
