Why is it important for signal transduction systems to trigger a rapid response within a cell and be able to be shut down quickly?

-All signal transduction cascades are shut down immediately so as to prevent the cell from mounting a response.

-Cells are unable to respond quickly to hormones, and therefore signal transduction cascades always occur over a long time.

-Cells have to be able to function alone, because they are unable to work together in a coordinated fashion.

-Cells often have to respond very quickly to changes in their internal and external environments.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
