What is exocytosis?

• The process of vesicles fusing with the cell membrane and releasing their contents inside the cell.

• The process of vesicles fusing with the cell membrane and releasing their contents into the bloodstream.

• The process of vesicles fusing with the cell membrane and releasing their contents outside the cell.
