Ecolink was right, they act as a channel for substances to go through.
Well, Car711, I remember facillitated diffusion is only for small substances (exocytosis, endodcytosis take care of large ones). Pores in the membrane are different kind of proteins.
Facillitated diffusion doesnt need ATP; however, it still needs proteins to help moving materials through the phospholipid membranes.
The carrier proteins are integral and peripheral proteins. They transport specific types of substances across intracellular compartments or in extracellular fluids (e.g. in the blood) or else across the cell membrane.
But remember, carrier proteins also help in active transport.

Carrier proteins act as channels to let materials go through.

carrier proteins help facillitated diffusion by the movement of different kinds of molecules that may be to large to pass through the pores of the membrane.

Carriers such as NADH and FADH help carrier the high energy electrons during cellular respiration.
They are a way of safely moving them around w/out disturbing their energy.
