Q

A
The transport of solid matter or liquid into a cell by means of a coated vacuole or vesicle.
3
Q
Protein Trafficking
A
This process is known as exocytosis.
1 Proteins synthesised
2 Protein enters rER cisternae
3 Protein is folded into 3D shape
4 Vesicles containing proteins pinch off rER
5 Vesicles travel to Golgi Body
6 Vesicles fuse with Golgi Body
7 Protein is modified
8 Vesicles containing modified proteins pinch off the Golgi Body
9 Vesicles move to cell/organelle membrane
10 Vesicles fuse with cell/organelle membrane
11 Contents of vesicles leave cell
