In active transport, carrier proteins are used, which use energy in the form of ATP, to:

(1) transport molecules against the concentration gradient of the cell wall.

(2) transport molecules along the concentration gradient of the cell membrane.

(3) transport molecules against the concentration gradient of the cell membrane.

(4) transport molecules along the concentration gradient of the cell wall.
