- Bulk Transport
- Exocytosis
- 1) vesicles from rough ER form Golgi, vesicles from Golgi
- 2) Vesicles fuse with plasma membrane and secretes contents
- Bulk transport of materials out of the cell
- Reverse of endocytosis
- Endocytosis
- 1) material causes plasma membrane to invaginate
- 2) enfold and eventually fuses forming a vesicle
- 3) lysosomes fuse with the vesicle and digest content
- Phagocytosis- solid material. Pinocytosis- liquid
- Substances eg hormones need to be released from the cell
- Type of active transport
- requires metabolic energy in the form of ATP
- For molecules that are too large to go through channel and carrier proteins
- Exocytosis
