permeable (has channels/transporters for specific ions/molecules)
plasma membrane
Plasma membrane
Large, polar, uncharged molecules cannot pass through a membrane without the help of protein channels embedded into the plasma membrane. Ions also have difficulty passing; they need ATPs.
The plasma membrane is somewhat like a filter system.It regulates the entry and exit of substances in and out of the cell.
They protect the cell, give it shape and regulates what goes in and out of the cell.
The cell membrane is a membrane separating the inside of the cell from the outside environment. This structure is also known as the plasma membrane or the cytoplasmic membrane.
it regulates the entry and exitof the molecules
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.)
No, the plasma membrane is a selectively permeable barrier that regulates the flow of most molecules across the membrane. The plasma membrane allows waste products to exit the cell and nutrients to enter the cell.
