The plasma membrane.
Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other.
The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)

One of the most important functions of the cell membrane is to?
The Cell Membrane protects the cell and regulates what substances enter and leave it. It is like the "gate keeper"
What cell main job is to control which substances enter and leave a plant cell.?
?
What maintains a chemical balance within a cell by regulating the materials that enter and leave the cell?
The Plasma membrane regulates what enters and exits the cell.
The part of the cell that regulates what can enter and leave?
The cell membrane determines what comes in and what goes out. Water goes in and out by osmosis which is a passive method. Others require the help of proteins that act as doorways. These require energy and the method is called active transportation.
What regulates what enter and leaves the cell?
The cell membrane
The nuclear envelope regulates which substances enter and leave a cell?
False

What acts as a barrier and decides which substances can enter and leave the cell?
The cell membrane.
What substances enter and leave the cells?
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
What regulates what can enter and leave the cell?
