Front

Osmotic pressure is...

Back

caused by the force of water molecules hitting the membrane on either side

Front

Active transport is

Back

movement of molecules from low concentration to high concentration using energy

Front

What is the function of protein pumps in cellular processes?

Back

use chemical energy to move ions (charged atoms) into or out of the cell

Front

Endocytosis is...

Back

use of a membrane pocket to move molecules into a cell
