Movement of Molecules and Cells

AB
Materials that are needed by the cell that move through their membraneswater, food and ions
Movement of molecules that does not require energypassive transport
Type of molecule movement that occurs when only certain types of molecules are allowed to pass through membrane channelsselective transport
Diffusion using a carrier moleculefacilitated diffusion
Movement of molecules that does require energyactive transport
The movement of molecules from an area of high concentration to an area of low concentrationdiffusion
the movement of molecules from an area of low concentration to an area of high concentrationactive transport
the movement of water from an area of high concentration to an area of low concentrationosmosis
Type of active transport that enables the cell to admit ions needed for important biological processes, such as the conduction of nerve impulsessodium-potassium pump
Type of active transport used to pump protons (H+ ions) across a membraneproton pump
the movement of large molecules into the cellendocytosis
the movement of large molecule out of the cellexocytosis
The process that uses the proton pump in the production of energychemiosmosis
