The main type of gates that regulate the flow of control signal substances into the Cell are called Cell surface receptors.
{Active transport of macromolecules into the Cell is not covered here.}
Exo-Active transport of the very many different types of biomolecules produced and exported from the Cytoplasm to the Cell's exterior is effected via the [cytoplasmic] Golgi Apparatus. This results in the copious production and use of membrane vesicle producing proteins - after export the membrane fragments are reassembled and the vesicle proteins are recycled.
Cell membrane
the cell membrane controls everything that enters or leaves a cell
It's the cell membrane that controls when enters and leaves a cell.
It controls what enters and leaves a cell, it also gives it support and shape.
food enters, waste leaves

The structure that controls traffic to and from the cell is the plasma membrane. It is not to be confused with the cell wall, which serves more to give structure to the cell.

It's like security guards for the White House because the membrane controls what enters and leaves the cell just like the security guards controls who enters and leaves the White House
