Selective permeability: Doesnât allow everything to pass through equally, has to have permission by the cell membrane e. Water is a molecule that can easily be passed through cell membrane without the help of carriers 13.Define/compare passive diffusion/active transport and simple/facilitated diffusion a. Active transport: moves molecules from lower concentration to higher with the help of ATP. Requires energy b.
Passive Transport: Simple Diffusion. Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. Remember that the cell membrane is a phospholipid bilayer. cell membrane is selectively permeable-not impermeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple or facilitated diffusion and osmosis.
