Movement Through the Cell Membrane • Lipid-soluble molecules pass through the cell membrane readily by dissolving in the lipid portion of the membrane. • Small molecules can pass through membrane channels. • Large molecules that are not lipid-soluble can be transported through the membrane by carrier molecules. • Large molecules that are not lipid-soluble, particles, and cells can be transported across the membrane by vesicles. Diffusion • Diffusion is the movement of a solute from an area of higher concentration to an area of lower concentration within a solvent. At equilibrium, there is a uniform distribution of molecules. • For a given distance, a concentration gradient is equal to the higher concentration minus the lower concentration of a solute in a solution....
