- Protein Trafficking AS Topic 2
- Protein transport within eukaryotic cells begins with amino acids being made into protein (on ribosomes)
- Newly-made protein is stored in rER (rough-endoplasmic reticulum) cavity
- Protein is packaged at the ENDS of rER.
- Membrane closes, forming a vesicle
- Vesicle pinches off the rER
- Floats towards Golgi Apparatus
- Protein is modified in the Golgi Apparatus (group of fluid-filled, flattened sacs)
- The proteins leave the cell by exocytosis
- The proteins leave the cell (exocytosis), when vesicles fuse with the cell surface membrane which contain extracellular enzymes
- The proteins leave the cell by exocytosis
- Protein is modified in the Golgi Apparatus (group of fluid-filled, flattened sacs)
