Cell Membranes and Transport

The fluid mosaic model describes the cell membrane as a phospholipid bilayer embedded with proteins.
Phospholipids are amphipathic; they have hydrophobic fatty acid tails and hydrophilic heads composed of a phosphate group and its attachments.
The cell membrane is selectively permeable. It is most permeable to small, nonpolar molecules and less permeable or impermeable to larger, nonpolar molecules and ions.
Passive transport does not require energy. Both simple diffusion and facilitated diffusion are methods of passive transport.
Osmosis is the diffusion of water down its concentration gradient.
Active transport requires energy in order to move a substance against its concentration gradient. Cotransport uses the energy of one substance moving down its concentration gradient to move a second substance against its concentration gradient.
Larger substances can enter the cell via endocytosis, in which the cell engulfs materials by pinching off a portion of the cell membrane to form a vesicle. Molecules may leave the cell via exocytosis.
