protein trafficking

• order of transport: T P F M T P E
• (T) Transcription - ribosomes fold proteins into their tertiary shape
• (P) Packaging - proteins are packaged into vesicles at the cisternae of the rER
• (F) Fusion - vesicles fuse with the Golgi Apparatus
• (M) Modification - the Golgi apparatus modifies proteins
• (T) Transferred - proteins are transferred to the secretory vesicles
• (P) Pinched - vesicles pinch off the Golgi apparatus
• (E) Exocytosis - vesicles fuse with the plasma membrane and release contents
