Column A 1. moves small molecules across the plasma membrane using
transport proteins
Column B
A. osmosis
B. exocytosis
2. involves water moving across the plasma membrane to the
side with the greater solute concentration
C. facilitated diffusion
3. occurs when substances move against the concentration
gradient; requires energy and the aid of carrier proteins
D. dynamic equilibrium
E. active transport
4. occurs when the plasma membrane surrounds a large
substance inside the cell and moves it outside the cell
F. endocytosis
5. the condition that results when diffusion continues until the
concentrations are the same in all areas
6. occurs when the plasma membrane surrounds a large
substance outside the cell and moves it inside the cell
