What are the three chief components of eukaryotic cell membranes? Where does each originate? What organelle synthesizes new membrane? What accounts for the stability of phospholipid bilayers in acqueos systems?
Is the ER the organelle that synthesizes new membrane?
The three chief components of the eukaryotic plasma membrane are: phospholipids, cholesterol, and proteins. Phospholipids originate from internal membrane systems such as the smooth ER. Cholesterol is likewise made inside the cell in the cholesterol biosynthetic pathway at ...
