Cell Transport Flashcards
What is the difference between passive transport and active transport?
Passive=no work by the cell
Active=requires work by the cell
What is it called when something moves from a crowded space to a more open space?
Diffusion
What is osmosis?
It’s when water molecules move through a membrane by diffusion
What is the name for diffusion that occurs through a specific channel in the cell membrane?
Facilitated diffusion (facilitated=assisted/helped)
What is it called when a vesicle works with the membrane to bring things into the cell?
Endocytosis (endo=in)
What is the opposite of endocytosis?
Exocytosis (exo=out)
Pump channels and endo/exocytosis are forms of what type of transport?
Active! They require work from the cell
What is the name of the chemical energy that allows active transport to happen? (3 letters)
ATP
