Cell Transport

This study stack was made to help you study active and passive cell transport.

QuestionAnswer
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
Exocytosis is what type of cell transport? Active or Passive? Active
Endocytosis is what type of cell transport? Active or Passive? Active
Ion Pump is what type of cell transport? Active or Passive? Active
Diffusion is what type of cell transport? Active or Passive? Passive
Osmosis is what type of cell transport? Active or Passive? Passive
Facilitated Diffusion is what type of cell transport? Active or Passive? Passive
