Secretory vesicles fuse with the cell membrane to release their contents to the outside of the cell. In this process, the membrane of the secretory vesicle becomes part of the cell membrane. Because small pieces of membrane are continually added to the cell membrane, we would expect the cell membrane to become larger and larger as secretion continues. However, the cell membrane stays the same size. Explain how this happens.

Question
Secretory vesicles fuse with the cell membrane to release their
contents to the outside of the cell. In this process, the membrane
of the secretory vesicle becomes part of the cell membrane. Because
small pieces of membrane are continually added to the cell membrane,
we would expect the cell membrane to become larger and larger as
secretion continues. However, the cell membrane stays the same
size. Explain how this happens.
