Cell Membranes
Cellular Transport
Active Transport
Carrier Protein
Vesicular transport
Bulk transport
Part of the cell membrane wraps around a molecule in a bubble ad pulls it into the cell
Moves with or against the concentration gradient
Passive Transport
Channel protein
Aquaporin
Used for transporting water
Moves with the cocentration gradient
Made of Phospholipids
Osmosis
Solutions
Hypotonic
More water goes into cell. Cell grows
Hypertonic
More water goes out of the cell. Cell shrinks
Isotonic
Water moves in and out of the cell equally. Cell stays the same size
Solvent
Solute
The movement of water into or out of a cell
Diffusion
Movement of molecules from a higher to a lower concentration
Molecules move through the cell membrane
Small, uncharged, polar molecules diffuse through the membrane without help
Other, larger, molecules move through the membrane with the help of different proteins
Concentration gradient
