A plasma membrane is made up of mostly a n _____.
Cell membrane is made up of mainly. Hydrophobic lipid layer c. The cell membrane consists of a lipid bilayer including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. The phospholipids are oriented so that their hydrophilic polar heads face outwards and their hydrophobic non-polar tails face inwards toward the middle of the cell.
The major part of the cell membrane is made up of phospholipids conformed to have the hydrophobic head out towards the water with the hydrophovic tails inward.
