Small, nonpolar molecules, like ---carbon dioxide , pass directly through the phospholipid bilayer. Charged particles, like ---ions eg H+,K+, can diffuse through the membrane if specific channel proteins are open. Some large, polar molecules, like ---glucose , can cross the membrane via facilitated diffusion. Small, polar molecules, like oxygen gas, can slip through small gaps in the phospholipid bilayer.
