Mediated Transport Across Cell Membranes

Mediated transport across cell membranes

A) Refers to the movement of ions through protein channels
B) Refers both to diffusion and to the active transport of molecules
C) Is characterized by saturable carriers and a maximum velocity of transport
D) Both refers to the movement of ions through protein channels and refers both to diffusion and to the active transport of molecules are correct
E) Both refers both to diffusion and to the active transport of molecules and is characterized by saturable carriers and a maximum velocity of transport are correct
