1) phosholipds
2) proteins (integral or surface)
3) cholesterol
4) carbonhydrates attach on the lipid or the protein
Cell membranes are made of a phospholipid bilayer, which is basically two lipids with a hydrophobic tail facing each other and a hydrophilic head surrounding the outsides. Proteins are embedded within the phospholipid bilayer and serve many purposes such as active transport.
Cell membranes are made of a phospholipid bilayer.
do protists have cell membranes?
Every microbe has cell membranes but only plants have plasma membranes...
Gradiend occurs between two places. Mainly either sides of membrane
It means nothing would be able to get through, mainly because all the proteins control the passage and what goes through, if there isn't any protein then the cell will be dead.
Lipid Bilayers
lipid bilayers
Cell membranes are mainly composed of phospholipids. A phospholipid is a phosphate group with a fatty acid tail. Proteins are also present in cell membranes.
Cell membranes are made of a phospholipid bilayer.
They are mainly located in the cell membranes but also can take tho form of steroids.
Cell membrane mainly consists of bilayer phospholipid which makes sure that nothing but water to pass through.

Molecules : membranes are mostly fats, most everything else is proteins. DNA is mainly sugars.

Yes all cells have cell membranes
