Passive and Facilitated Transport Mechanisms Consider these ions and molecules. Where would they pass through the cell membrane? Drag each to the correct location.

Our cells are continually moving things in and out. When this happens without the expenditure of cellular energy, with the concentration gradient, we call this passive transport. If the movement of molecules or ions requires a protein channel of some sort, it is called facilitated transport, still requiring no energy.
