The molecules in the membrane that limit its permeability are the:
Open in App
Solution
The correct option is B Phospholipids
Plasma membrane is the outermost covering of the cell which is made up of phospholipids bilayer and proteins.
Phospholipids in lipid bilayer limit the permeability of the membrane. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. Phospholipids provide barriers in cellular membranes to protect the cell, and they make barriers for the organelles within those cells. Phospholipids work to provide pathways for various substances across membranes.
