The Endomembrane System
Captions available
The idea
The endomembrane system is a group of organelles — nuclear envelope, ER, Golgi, lysosomes, vesicles, plasma membrane — modifying, packaging, and transporting lipids and proteins.
In practice
A protein made in the ER can travel by vesicle to the Golgi, then to the plasma membrane, without leaving this network.
Where people slip
Mitochondria and chloroplasts sit outside this system.
