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.
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.eceptor-mediated endocytosis occurs when the material to be transported binds to certain specific molecules in the membrane. Examples include the transport of insulin and cholesterol into animal cells. Endocytosis and exocytosis.
