Question | Answer |
Equilibrium | The state reached when molecules are evenly distributed throughout an area |
Concentration gradient | The difference in the number of molecules from one area to another |
Semi-permeable membrane | Some materials will go through it; some won't. |
Impermeable membrane | Materials will not go through it. |
Permeable membrane | Materials will go through it. |
Active transport | The movement of materials across a membrane that requires energy. |
Passive transport | The movement of materials across a membrane that does not require energy |
Diffusion | The random movement of molecules throughout an area that does not require energy. |
Osmosis | The diffusion of water across a membrane from an area of high concentration to a low concentration |
Facilitated diffusion | Type of passive transport that uses a transport protein to move large molecules from a high concentration to a low concentration |
Ion pump | A type of active transport that uses a transport protein and ATP energy to pump materials from a low concentration to a high concentration |
Endocytosis | A process of using a vesicle to bring materials into the cell |
Exocytosis | A process of using a vesicle to release materials from the cell |
