The Importance Of Channel Proteins In Cell Communication

WebbIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport. WebbThe Plasma Membrane. Like prokaryotes, eukaryotic cells have a plasma membrane ( Figure 3.8) made up of a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. A phospholipid is a lipid molecule composed of two fatty acid chains, a glycerol backbone, and a phosphate group. sharon lettman hicks wikipedia
