Endomembrane System • Lots of parts working together • Analogy- the membrane is like a moving sidewalk, a molecule in the membrane would go to from the nuclear envelope to the ENDOPLASMIC RETICULUM, then a TRANSPORT VESICLE, then to the GOLGI BODY (the transport vesicle will fuse with the golgi body), MEMBRANE defuses with the golgi body, may go to the LYSOSOME (not likely to be part of the cell membrane) • Made for export will be made in the rough ER • Only in a eukaryote • ARE ALL ORGANELLES PART OF ENDOMEMBRANE SYSTEM? • Prokaryotes do not have membrane-bound organelles!! • Vesicle • Central Vacuole- o fluid filled o amino acids, sugars, wastes o may expand to 50-90% of cell o help plant cells be strong and supportive by being filled with water and expanding. o Animal cells do NOT have central vacuoles • Mitochondria o ATP-producing powerhouses o Double-membrane system o Animals have only mitochondria, plants have them AND chloroplasts...
