WebMar 5, 2024 · Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Instead, they diffuse across the membrane through transport proteins. WebAnswer: Different membrane proteins are associated with the membranes in different ways. Many extend through the lipid bilayer, with part of their mass on either side. Like their lipid neighbors, these transmembrane proteins are amphipathic, having regions that are hydrophobic and regions that ar...
