A cell membrane is made up of lipids (the lipid bilayer) was well as glycoprotiens and glycocalyses. The proteins can be on either or bothe sides of the lipid bilayer, allowing for various types of transport through the "semi-permeable membrane." The proteins on the surface may be used for identification purposes.

How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
What are the molecules that give the cell membrane a mosaic structure?
protein molecules in the cell membrane gives the mosaic structure .
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Why do passenger molecules need to be helped by the carrier protein?
Some molecules can't go through the cell membrane.
The cell membrane contains lipid molecules that?
The cell membrane contains lipid molecules that provide a barrier to the free movement of ions into and out of the cell.
Which part of the cell surrounds the cell and allows molecules in and?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
What do cell membrane do that cell walls can't do?
Cell membrane is selectively permeable membrane, therefore it allows selective molecules to be taken in by the cell and excludes others. Whereas cell wall is permeable in nature and does not inhibit the intake of many molecules what the cell membrane does.
Molecules move into and out of a cell though the?
Cell Membrane
The part of the cell that is in most direct contact with the environment is the?
The cell membrane, which surrounds the cell and is responsible for which molecules are allowed to diffuse into or out of the cell and which molecules are impermeable to the membrane
What part of the cell membrane allows small molecules to pass through?
the cell membrane
Which part of the cell surrounds the cell and allows molecules in and out this cell part also has holes in it and is said to be semi-permeable?
The cell membrane is the thing that surrounds the cell. The cell membrane contains proteins that allow active transport of molecules in and out of the cell.
