Which of the following describes a form of passive transport? A. Membrane proteins act as an enzyme to break down ATP and use the energy to move particles against the concentration gradient

B. Large molecules are brought into the cell by wrapping the cell membrane around molecules to form a vacuole

C. Membrane proteins use the energy of the cells resting potential to move against the concentration gradient

D. Membrane proteins provide a pathway for larger particles to move across the cell membrane and bring the cell and environment closer to equilibrium
