Part C Facilitated diffusion doesnt require energy from the cell, so its also a form of passive transport. Thus, over time, the net movement of molecules will be out of the more concentrated area and into the less concentrated one, until the concentrations become equal (at which point, its equally likely for a molecule to move in either direction). Two major classes of facilitated transport proteins are channels and carrier proteins. Polar and charged molecules have much more trouble crossing the membrane.

Lipids, such as these yellow molecules, can dissolve in the lipid bilayer. Amphipathic nature chamber. is present. This is because channel proteins are simple tunnels; unlike carrier proteins, they dont need to change shape and reset each time they move a molecule. Start typing, then use the up and down arrows to select an option from the list. This process does not require any energy input; in fact, a concentration gradient itself is a form of stored (potential) energy, and this energy is used up as the concentrations equalize. Channels typically transport water or inorganic ions, whereas carrier proteins typically transport small polar molecules such as sugars or where T is the absolute temperature.
