WebDec 18, 2016 · Membrane proteins are required for facilitated diffusion of charged and large polar molecules through a membrane – Large quantities of water pass through aquaporins. Charged ions, including Na + and K +, require channel proteins to move through the membrane. Membranes may become polarized by movement of ions … WebIon Channels Allow Ion Movement. Embedded throughout the neuronal membrane are ion channels. Ion channels are proteins that span the width of the cell membrane and allow charged ions to move across the membrane. Ions cannot pass through the phospholipid bilayer without a channel. Channels can be opened in a number of different ways. how did steve know bucky killed the starks
