Study Notes
Endosomes
- Endosomes are membrane-bound vesicles that act as sorting stations for materials taken up from the cell's exterior through endocytosis.
- These vesicles collect soluble macromolecules and sort them for further processing.
- Some membrane proteins are recycled back to the plasma membrane, while others are transported to late endosomes.
- Late endosomes further sort the internal contents and deliver them along with their membrane to lysosomes for degradation.
