What is true of ions and their transport across cell membranes?
electrical or chemical signals may control the movement of ions across cell membrane
Controls the movement of molecules into and out of the cell?
To put it simply, it is the cell membrane. You can have transport vesicles ect, but the cell membrane is the main barrier between inside and outside. It contains pumps, channels and proteins that are in charge of communication and also control movement of everything from inside and outside. hhh
What are the 2 main parts of the cell membrane?
The cell membrane is formed by a double-layer of molecules known as phospholipids. It is therefore known as a phospholipid bilayer.
What structure controls the passage of substances into and out of the cell?
cell membrane
Where is the cell control center and the cell membrane?
where is the cell control membrane and the cell membrane
What is in charge of what enters and leaves the cell?
The cell membrane

What is the electrical charge transmitted along the muscle cell membrane after stimulation?
Tonus
What regulates passage of materials into and out of cells?
The cell membrane controls movement of materials in and out of the cell.
Which cell structure controls what enters and leaves the cell?
The selective permeability of the cell membrane
What cell structures are made primarily from phospholipids?
cell membrane
What structure controls the passage of substances into and out of the cell?
cell membrane
What controls entry into and out of the cell?
Cell Membrane
What is the thin flexible membrane around all cells?
the cell membrane is as flexible barrier outside of the cell.
What is a factor that deteremines whether a molecule can cross a cell membrane?
Usually its size and net charge.
