Transport Practice

Which one is the definition of active transport?

• movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.

• passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane

• net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient
