Movement through the Cell Membrane The cell membrane is selectively permeable, allowing some substances to pass through it, but not others.Match these terms with the correct statement or definition:Carrier molecules Membrane channels Lipid bilayer Vesicles1 Molecules that are soluble in lipids dissolve in this.—Lipid Bilayer2 Allow molecules of only a certain size range to pass through. Membrane Channels3 Large molecules that are not lipid-soluble are transported by these proteins.—Carrier Molecules4 Membrane-bound sacs that transport large nonlipid-soluble molecules, small pieces of matter, and even whole cells.---Vesicles5 Sodium and potassium ions are transported through these. Active Transport Pump6 Glucose and amino acids are transported by these.-Facilitated DiffusionBecause of the membrane's permeability characteristics and its ability to transport certain molecules, cells are able to maintain proper intracellular concentrations of molecules.Diffusion Diffusion is an important means by which substances move through the extracellular andintracellular fluids in the body.Match these terms with the correct statement or definition: Diffusion Solvent Solute1 Predominant liquid or gas in a solution.-- Solvent2 Substance dissolved in the solvent.—Solute
