The diagram shows two chambers with different concentration of molecules separated by a selectively permeable membrane. Predict what will happen to the water molecules ?

• move from B to A due to diffusion

• move from B to A due to osmosis

• move from B to A due to active transport

• move from A to B due to osmosis

Active transport is movement of particles through the cell membrane from a region of ...1... to a region of ...2... using energy in the form of ...3...

• 1: lower concentration, 2: higher concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: NADPH

• 1: higher concentration, 2: lower concentration, 3: ATP

• 1: lower concentration, 2: higher concentration, 3: ATP
