text: To control the amount of certain molecules that enter and exit the cell
text: It is possible for large molecules to enter a cell by a process called endocytosis, where a small piece of the cell membrane wraps around the particle and is brought into the cell.
text: The shape of the membrane itself changes to allow molecules to enter or exit the cell.
text: Proteins are wedged between the lipids that make up the membrane, and these transmembrane proteins allow molecules that couldn’t enter the cell otherwise to pass through by forming channels, pores or gates.
text: The nature of the phospholipids in the membrane helps keep it fluid and semi-permeable, so that some molecules like oxygen, carbon dioxide and small hydrocarbons can move through it and enter the cell, while other molecules that might be harmful or unneeded by the cell are kept out.
text: The cell membrane functions like a gate, controlling which molecules can enter and leave the cell.
text: It is a semi-permeable or selectively-permeable membrane that encloses the contents of a cell, allowing only selected molecules to enter the cell and blocking out the others.
text: Yes, it does restrict many molecules from entering (or leaving) the cell, but it is also designed so that some molecules can very quickly move through the membrane, and thus enter or leave the cell with ease.
text: (i.e. the medium is a isotonic solution) there will exist a dynamic equilibrium between the number of molecules of water entering and leaving the cell and so the cell will retain its original size.
text: (i.e. the medium is a isotonic solution) there will exist a dynamic equilibrium between the number of molecules of water entering and leaving the cell and so the cell will retain its original size.
text: The resulting structure is termed a lipid bilayer which mediates molecules that enter or leave the cell.
text: Charged or polar molecules that cannot fit between the phospholipids generally enter and leave cells through facilitated diffusion.
