본문내용

The Role of Exocytosis for Cells’ Function

To release toxins, waster products and large molecules such as proteins
Proteins are produced in ribosome and enclosed in a vesicle in Golgi apparatus
Then vesicles are able to move to the surface transporting protein
Eventually, vesicles fuse with the membrane, releasing proteins to the external

Nerve cells, endocine cells release such substances controlling other cells through the “Excocytosis” mechanism
