Unit 2 Vocabulary

Front

Cellular Transport

Back

the movement of molecules across the cell membrane

Front

Selective Permeability

Back

the ability to control what enters and leaves the cell

Front

Concentration Gradient

Back

gradual change in concentration from high to low

Front

Active Transport

Back

use of energy (ATP) to move molecules against the concentration gradient from low to high

Front

Cell Membrane

Back

the outer layer of the cell that controls what enters and leaves

Front

Endocytosis

Back

transport of large molecules into the cell via a vesicle

Front

Exocytosis

Back

transport of large molecules out of the cell via a vesicle

Front

Passive Transport

Back

movement of molecules/particles with the concentration gradient from high to low across the cell membrane

Front

Diffusion

Back

random movement of particles from high to low concentration

Front

Facilitated Diffusion

Back

type of passive transport where molecules move across the cell membrane with the aid of a protein channel
