What does the plasma membrane do?

Answer 1

The plasma membrane is like the skin of the cell and lets only certain things in and out. It uses active and passive transport to let things in and out meaning that it uses energy only sometimes to let things in and out (this being active) and lets things move as they please at other time (this being passive)

Answer 2

Plasma membrane functions to hold the contents of a cell together and separates them from the external environment.

Plasma membrane also selectively controls the movement of substances going in or out of the cytoplasm, both actively and passively.

Answer 3

The cell membrane/plamsa membrane a) maintains the internal environment of the cell by monitoring what enters and exits it b) Contains the contents of the cell, and c) Lends some sort of protection to the cell.

Answer 4

They do several things, depending on what they are designed for. The plasma membrane is made up of proteins which are semi-permeable to the outside and hold the cytoplasm within the cell and help to either prevent or allow diffusion of various substances into or out of the cell. They may also form receptor sites along the membrane for the attachment of enzymes which facilitate diffusion of certain substances.

Answer 5

Proteins interacts with the lipidic environment of the plasma membrane. The lipids affect the proteins and viceversa. Proteins may change the permeability of the plasma membrane to ions, organize lipid rafts, etc.

Answer 6

Plasma membrane works when all the stars in the universe collide...... Nahh I'm punking with yahh idk ask a nerd >.> sheesh
