Cell Transport Flashcards
semi permeable or selectively permeable
a cell membrane that allows some things to go through and some not
Diffusion
the molecules movement from high to low that doesn’t require atp energy
Osmosis
the movement of water from high concentration to low concentration through a membrane
Passive Transport
Movement through the membrane from high to low concentration that doesn’t require energy
Active Transport
Movement across the cell from low to high concentration that uses atp energy
Endocytosis
Process of a cell taking in substance using atp energy
Exocytosis
Process of a cell getting rid of a substance by releasing vesicles that vary the substance outside of the cell using ATP energy
Hydrophilic
Water loving (when an element and water do work)
Hydrophobic
Water hating (when an element and water don’t mix)
Phospholipid bilayer
the layers of the cell that protect it from the environment
Channel protein
a type of passive transport where substances movement from high to low concentration through a channel in the membrane not using ATP energy
Carrier protein
a type of active transport where larger substances move from low to high concentration using ATP energy
Concentration Gradient
The natural flow of molecules from high to low concentration
